A Hollow

A hollow steel compression member needs to support a 1500 kip load with a safety factor of 8. Given an outer diameter of 2 times the inner diameter, the problem is to determine the inner and outer diameters required. A simple beam made of cast steel needs to support a center distributed load. The problem is to determine the beam dimensions for a safety factor of 3, and to calculate the maximum deflection for those dimensions. An additional part asks for dimensions if the maximum deflection cannot exceed 0.03 inches. A 10hp electric motor drives a centrifugal pump via a steel shaft. The problem is to recommend the shaft diameter required, given the material properties and that the shaft only rotates in a clockwise motion

A hollow, short compression member, of normalized cast steel (ASTM A27-58, 65 ksi), is to support a load

of 1500 kips with a factor of safety of 8 based on the ultimate strength. Determine the outside and inside
diameters if Do = 2Di.

A simple beam 54 in. long with a distributed load of 4 kips/in at the center is made of cast steel, SAE 080.
The cross section is rectangular (let h = 3b). (a) Determine the dimensions for N = 3 based on the yield
strength. (b) Compute the maximum deflection for these dimensions. (c) What size may be used if the
maximum deflection is not to exceed 0.03 in.? For cast steel, SAE 080 (Table AT 6) s y = 40 ksi & E =
30×106 psi
A 10hp, 800rpm electric motor drives a centrifugal pump by means of a shaft that is made of AISI
C1035(Su = 85ksi, Sy = 55ksi), Normalize steel. Recommend the shaft diameter required if shaft only
rotate clockwise motion.
