Problem 324 | Equilibrium of Three-force System

Problem 324
A wheel of 10-in radius carries a load of 1000 lb, as shown in Fig. P-324.
 

Wheel to roll over a block

 

(a) Determine the horizontal force P applied at the center which is necessary to start the wheel over a 5-in. block. Also find the reaction at the block.

(b) If the force P may be inclined at any angle with the horizontal, determine the minimum value of P to start the wheel over the block; the angle P makes with the horizontal; and the reaction at the block.
