Concept explainers

Slope and Deflection

The slope in a deflected beam is described as an angle in radians made by the tangent of the section with the original axis of the beam. The deflection at any point on the axis of the beam is defined as the lateral displacement of the point before and after loading.

Question

2. Two shafts, one solid the other one hollow, are connected end to end by means
of a coupling in which there are 8 screws on the pitch diameter D = 250 mm.
The solid shaft has diameter d = 50 mm and transfers the power P = 500 kW at 75 rev/s.
The external diameter of the hollow shaft is dex = 75 mm.
%3D
Note: All parts of the system must be equally strong, and able to transfer the required
power
Calculate:
(a)
The internal diameter d; of the hollow shaft
(b)
The diameter of the bolts d, connecting the two shafts
(c)
If the hollow shaft has to be replaced by a rectangular hollow cross-section with
outer dimensions b xh and uniform wall thickness of 4 mm.
Calculate the values b, h while following the request to keep h = 2b
