The platform assembly has weight W1 and center of gravity

The platform assembly has weight W1 and center of gravity at G1. If it is intended to support a maximum load W2 placed at point G2, determine the smallest counterweight W that should be placed at B in order to prevent the platform from tipping over.

Given:

W1 = 250 lb a = 1 ft c = 1 ft e = 6 ft

W2 = 400 lb b = 6 ft d = 8 ft f = 2 ft
