Problem 1.

Design a shear pin for the propeller shaft of an

outboard motor if the shaft through which the

pin is placed is 25-mm diameter, the propeller is

20-cm diameter, and the pin must fail when a

force > 400 N is applied to the propeller tip.

Assume an ultimate shear strength for the pin

material of 100 MPa.
