Chapter 4, Problem 133P

Replace the force system acting on the beam by an equivalent force and couple moment at point A. foroo A 2 m 36 kN 3 m d along the positive u 20 KN Co 2 m B 94 kN.m

d= 3.8m (on the figure of the beam) Determine the equivalent resultant force and determine the equivalent couple moment at point O.

1. the tow truck's front wheels will belifted off the ground if the moment of the load W about the rear axle exceeds the moment of 3000N weight of the truck. Determine the largest w that may be safely applied   2. the flat plate shown in the figure is acted on by the three couples. replace the three couples with two forces, one acting along the line OP
