The compound-lever pruning shears shown can be adjusted by placing pin A at various ratchet positions on blade ACE. The length AB is 0.85 inches. Write a computer program and use it to determine the magnitude of the vertical forces applied to the small branch for values of d from 0.4 in to 0.6 in using 0.025 inch increments. As a part of the design of the shears, use appropriate smaller increments and determine the smallest allowable value of d if the force in link AB is not to exceed 500 lbs.
