For the allen wrench of Problem 7.15, what is the deflection of the tip of the wrench when the maximum load of 60 N is applied, just before the bolt loosens?
Problem 7.15:
The maximum force applied to the tip of the allen wrench before the bolt loosened is 60 N. Assume the wrench has a circular cross section with a radius 2 mm. The length of the short segment (touching the screw) is 3 cm and the length of the long segment (to which the force is applied) is 6 cm. Write the stress tensors at points Aand B, both of which are on the top (z-facing surface) of the wrench. Hint: you will need to use some results from Chapter 5.
