1. The cutter of a broaching machine is pulled by square threaded screw of 55mm external

diameter and 10 mm pitch. The operating nut takes the axial load of 400 N on a flat
surface of 60 mm internal diameter and 90 mm external diameter. If the coefficient of
firction is 0.15 for all contact surfaces on the nut, determine the power required to
rotate the operating nut, when the cutting speed is 6 m/min.
2.

The mean diameter of the screw jack having pitch of 10 mm is 50 mm. A load of 20 kN is
lifted through a distance of 170 mm. Find the work done in lifting the load and efficiency of
the screw jack when

1. the load rotates with the screw, and

2. the load rests on the loose head which does not rotate with the screw.
The external and internal diameter of the bearing surface of the loose head are 60 mm
And10m respectively. The coefficient of friction for the screw as well as the bearing
surface may be taken as 0.08.
3. A rotor is driven by a co-axial motor through a single plate clutch, both sides of the plate
being effective. The external and internal diameters of the plate are respectively 220 mm and
160 mm and the total spring load pressing the plates together is 570 N. The motor armature
and shaft has a mass of 800 kg with an effective radius of gyration of 200 mm. The rotor has a
mass of 1300 kg with an effective radius of gyration of 180 mm. The coefficient of friction
for the clutch is 0.35. The driving motor is brought up to a speed of 1250 r.p.m. when the
current is switched off and the clutch suddenly engaged. Determine

1. The final speed of motor and rotor,

2. The time to reach this speed, and 3. The kinetic energy lost during the period of
slipping.How long would slipping continue if it is assumed that a constant resisting
torque of 60 N-m were present? If instead of a resisting torque, it is assumed that a
constant driving torque of 60 N-m is maintained on the armature shaft, what would
then be slipping time?

Turning moment diagrams

1. The turning moment diagram for a petrol engine is drawn to the following scales : Turning
moment, 1 mm = 5 N-m ; crank angle, 1 mm = 1. The turning moment diagram repeats itself
at every half revolution of the engine and the areas above and below the mean turning
moment line taken in order are 295, 685, 40, 340, 960, 270 mm 2. The rotating parts are
equivalent to a mass of 36 kg at a radius of gyration of 150 mm. Determine the coefficient of
fluctuation of speed when the engine runs at 1800 r.p.m.
2. During forward stroke of the piston of the double acting steam engine, the turning moment
has the maximum value of 2000 N-m when the crank makes an angle of 80 with the inner
dead centre. During the backward stroke, the maximum turning moment is 1500 N-m when
the crank makes an angle of 80 with the outer dead centre. The turning moment diagram for
the engine may be assumed for simplicity to be represented by two triangles. If the crank
makes 100 r.p.m. and the radius of gyration of the flywheel is 1.75 m, find the coefficient of

fluctuation of energy and the mass of the flywheel to keep the speed within
0.75%of the mean speed. Also determine the crank angle at which the speed has its
minimu and maximum values.
3. The turning moment diagram for a four stroke gas engine may be assumed for simplicity to be
represented by four triangles, the areas of which from the line of zero pressure are as follows :
Suction stroke = 0.45 103 m2; Compression stroke = 1.7 103 m2; Expansion stroke =
6.8 103 m2; Exhaust stroke = 0.65 103 m2. Each m2 of area represents 3 MN-m of
energy. Assuming the resisting torque to be uniform, find the mass of the rim of a flywheel
required to keep the speed between 202 and 198 r.p.m. The mean radius of the rim is 1.2 m.
4. A certain machine requires a torque of (5000 + 500 sin ) N-m to drive it, where is the
angle of rotation of shaft measured from certain datum. The machine is directly coupled to an
engine which produces a torque of (5000 + 600 sin 2) N-m. The flywheel and the other
rotating parts attached to the engine has a mass of 500 kg at a radius of gyration of 0.4 m. If
the mean speed is 150 r.p.m., find : 1. the fluctuation of energy, 2. the total percentage
fluctuation of speed, and 3. the maximum and minimum angular acceleration of the flywheel
and the corresponding shaft position.

Governers
1. In an engine governor of the Porter type, the upper and lower arms are 200mm and 250 mm
respectively and pivoted on the axis of rotation. The mass of the central load is 15 kg, the
mass of each ball is 2 kg and friction of the sleeve together with the resistance of the
operating gear is equal to a load of 25 N at the sleeve. If the limiting inclinations of the upper
arms to the vertical are 30 and 40, find, taking friction into account, range of speed of the
governor.
2. The arms of a Porter governor are 300 mm long. The upper arms are pivoted on the axis of
rotation. The lower arms are attached to a sleeve at a distance of 40 mm from the axis of
rotation. The mass of the load on the sleeve is 70 kg and the mass of each ball is 10 kg.
Determine the equilibrium speed when the radius of rotation of the balls is 200 mm. If the
friction is equivalent to a load of 20 N at the sleeve, what will be the range of speed for this
position ?
3. A Proell governor has all four arms of length 305 mm. The upper arms are pivoted on the axis
of rotation and the lower arms are attached to a sleeve at a distance of 38 mm from the axis.
The mass of each ball is 4.8 kg and are attached to the extension of the lower arms which are
102 mm long. The mass on the sleeve is 45 kg. The minimum and maximum radii of governor
are 165 mm and 216mm. Assuming that the extensions of the lower arms are parallel to the
governor axis at the minimum radius, find the corresponding equilibrium speeds.
4. In a spring loaded Hartnell type governor, the extreme radii of rotation of the balls are 80 mm
and 120 mm. The ball arm and the sleeve arm of the bell crank lever are equal in length. The
mass of each ball is 2 kg. If the speeds at the two extreme positions are 400 and 420 r.p.m.,
find : 1. the initial compression of the central spring, and 2. the spring constant.

Balancing of rotary and reciprocating masses

1. A shaft carries four masses A, B, C and D of magnitude 200 kg, 300 kg, 400 kg and 200 kg
respectively and revolving at radii 80 mm, 70 mm, 60 mm and 80 mm in planes measured
from A at 300 mm, 400 mm and 700 mm. The angles between the cranks measured
anticlockwise are A to B 45, B to C 70 and C to D 120. The balancing masses are to be
placed in planes X and Y. The distance between the planes A and X is 100 mm, between X
and Y is 400 mm and between Y and D is 200 mm. If the balancing masses revolve at a radius
of 100 mm, find their magnitudes and angular positions.
2.

A shaft is supported in bearings 1.8 m apart and projects 0.45 m beyond bearings at each end.
The shaft carries three pulleys one at each end and one at the middle of its length. The mass
of end pulleys is 48 kg and 20 kg and their centre of gravity are 15 mm and 12.5 mm
respectively from the shaft axis. The centre pulley has a mass of 56 kg and its centre of
gravity is 15 mm from the shaft axis. If the pulleys are arranged so as to give static balance,

5. The turning moment diagram for a petrol engine is drawn to the following scales : Turning moment, 1
mm = 5 N-m ; crank angle, 1 mm = 1. The turning moment diagram repeats itself at every half

are 295, 685, 40, 340, 960, 270 mm2. The rotating parts are equivalent to a mass of 36 kg at a radius of
gyration of 150 mm. Determine the coefficient of fluctuation of speed when the engine runs at 1800
r.p.m.

maximum value of 2000 N-m when the crank makes an angle of 80 with the inner dead centre. During
the backward stroke, the maximum turning moment is 1500 N-m when the crank makes an angle of 80
with the outer dead centre. The turning moment diagram for the engine may be assumed for simplicity
to be represented by two triangles.

stroke = 0.45 103 m2; Compression stroke = 1.7 10 3 m2; Expansion stroke = 6.8 10 3 m2;
Exhaust stroke = 0.65 103 m2. Each m2 of area represents 3 MN-m of energy. Assuming the
resisting torque to be uniform, find the mass of the rim of a flywheel required to keep the speed
between 202 and 198 r.p.m. The mean radius of the rim is 1.2 m.

engine has a mass of 500 kg at a radius of gyration of 0.4 m. If the mean speed is 150 r.p.m., find : 1.

minimum angular acceleration of the flywheel and the corresponding shaft position.
