The block A and the wedge B weighs 100 kN and 40 kN, respectively. The coefficient of friction for all contacting surfaces is u = 0.268. Determine the following: a. What value of P in kN would be required to push to the right the wedge under the block? b. What value of P in kN would be required to pull to the left the wedge under the block? Assume the block A is still in contact with the wall just as motion starts.
