Hi i need some help on solving a question from a past paper. I am revising for an exam in applied engineering mechanics.
Question:
A screwdriver is designed so that the bit is 5mm wide and 1mm deep and is 25mm long, this is welded to a cylindrical bar 12mm in diameter and 100mm long. If the maximum twist allowable is 1 degree and the allowable shear stress within the bar is 40MPa and G=80Gpa. Determine the maximum torque that the screwdriver can transmit.
You are also given a table of coefficients for rectangular bars in torsion
