Lever Calculation: Taking Material: C60 Steel FS 5, Syt 400N/mm Sy/f 80N/mm T 0.5syt/ F 40N/ MM

This document describes the calculation of forces acting on a lever made of C60 steel with a yield strength of 400N/mm2 and a tensile strength of 80N/mm2. The fulcrum is located at the center of the cylinder head. The lengths of the two arms of the lever are 405mm and 25mm. The total force acting on the lever equals the sum of the force at the fulcrum from the piston rod weight and the force on the first and second linkages of the lever. The calculation also determines the cycle speed in terms of revolutions per minute based on an angle of swing of 75 degrees and a diameter of 810mm.

LEVER CALCULATION

Taking Material: C60 Steel

FS = 5, Syt = 400N/mm2

σ t = Sy/fs = 80N/mm2

T = 0.5Syt/ fs = 40N/ mm2

Schematic Sketch of forces acting on a lever

Taking Fulcrum will be at the center of Cylinder Head

l1= 405mm
l2= 25 mm ,Half of Cylinder Diameter to provide balance

Calculation of forces acting on Lever:

F = R+P1

Where

F= Force acting on Lever

P1 = Force on the first bar linkage and second bar linkage

R = Force acting at Fulcrum ,Weight of piston rod


Calculation speed in terms of cycle

Θ = 75° , Angle of full swing

D = 810mm
