A 300 lb box is held at rest on a smooth plane by a force P inclined at an angle θ with the plane as shown in Figure. If θ = 45°, determine the value of P and the normal pressure N exerted by the plane.
- P = 221.13 lb, N = 904.81 lb
- P = 122.12 lb, N = 409.81 lb
- P = 212.13 lb, N = 409.81 lb
- Cannot determine
Answer
(C) P = 212.13 lb, N = 409.81 lb
