Determining the maximum vertical acceleration given to a pipe, and the normal reactions acting on the wheels.
Kinetics of Rigid Body
I) the forklift and operator have a combined weight of 10000 lb and a center of gravity at G. If the forklift is used to lift the 2000-lb concrete pipe, establish the utmost vertical acceleration it can give to the pipe so that it does not tip forward on its front wheels.
II) The forklift and operator have a combined weight of 10000 lb and a center of gravity at G. If the forklift is used to lift the 2000-lb concrete pipe, find out the normal reactions on each of its four wheels if the pipe is given an upward acceleration of 4 ft/s2.
