A block (with mass M) is resting on an inclined plane, and is attached to the wall by a cord (see figure). The block is pulled by an applied force F (horizontal) on the lower side. The inclined plane is frictionless and makes an angle 0 with the horizontal. Use g = 9.81m/s². (a) Draw a free body diagram for the block. Label and state all the forces on the block. F: Applied force (b) Write down all the forces in unit-vector notation in terms of their magnitudes (in variables) and the inclined angle 0. F = F cos 0 î + F sin 0 § (c) Find the magnitude of the tension in the cord (in terms of known variables: F, M and 0). [Use the fact that EF = 0.] (d) Find the normal force acting on the block (in terms of known variables: F, M and 0). [U the fact that EF, = 0.]
