Problem $1$quad $(100$ marks$)$ Design problem: Design a heat$-$treated steel shaft to support a spur gear

and an overhanging worm, as illustrated in the figure. The bearing at point A is subjected to pure

radial load, while the bearing at point B supports the worm thrust load for both directions of

rotation. The figure includes the dimensions and loading conditions, with radial loads in the same

plane. Your task is to perform a complete design of the shaft, including:

A detailed sketch of the shaft with all dimensions clearly labeled $($using any CAD software$)$

marks$)$

Selection of a suitable material and, if required, the recommended heat treatment process. $(10$

marks$)$

An evaluation of the final design, addressing aspects such as strength, deflection, and service life.

$(60$ marks$)$

Quality of design report. $(10$ marks$)$ The shaft operates at a speed of $310$ revolutions per

minute $($rev$/$min$).$ All dimensions are provided in pillimeters$($mm$).$ Bonus $(15$ marks$)$: Any additional

effort such as finite element analysis or prototy

$($all other solution on chegg is wrong provide me with a flie for cad drawing and solve it with detail dont use hand writing $)$
