3.3.2 Shaft Design

   In this section, applying basic calculation and MITCALC program in order to find the proper
   diameter of the shaft, a simulation of the shaft was perform.

Wa: Weight of the car at a (75         9.81   /  2)
Wb: Weight of the car at b (75         9.81   /  2)
T: chain force ( 322.4 N)
