Problem Statement:

The shaft in the figure below is part of a conveyor drive system that feeds crushed rock into a railroad car. The shaft rotates at $240$ rpm and is subjected to moderate shock during operation. All power is input to the gear at $D.$ The V$-$belt sheave at A delivers $10\mathrm{.}0$ hp vertically downward. Chain sprocket $E$ delivers $5\mathrm{.}0$ hp $.$ Note the position of the gear $Q,$ which drives gear $D.$

$1.$If these are the answers draw shear and moment diagram

$2.$ Computing the minimum acceptable diameter at each point on the shaft and choosing the proper diameters for all key points to be implemented in the design.

$TD=445\mathrm{.}037Nmm$

TA$=296\mathrm{.}7$Nmm

$TE=148\mathrm{.}352Nmm$
