To review, the process for solving inclined plane problems is as follows: Draw a sketch of the problem. Identify known and unknown quantities, and identify the system of interest. Draw a free-body diagram (which is a sketch showing all of the forces acting on an object) with the coordinate system rotated at the same angle as the inclined plane.4. A truss supports the loading shown. Determine the equivalent force acting on the truss and the point of intersection of its line of action with a line through points A and G. Answer: a) R = 773 N at 259o. b) d = 9.54 m to the right of A. 5. Three forces and a couple act on crank ABC. For P = 5 lb and ( = 400, friction. Blocks l and 2 move with a constant velocity v down the inclined plane, which makes an angle θ with the horizontal. The kinetic frictional force on block 1 is f and that on block 2 is 2f. a. On the figure below, draw and label all the forces on block m l. Express your answers to each of the following in terms of m l, m 2, g, θ, and f. When an object sits on a frictionless incline plane, the two forces acting on the object are the gravitational pull of the earth, its weight, mg, and the supporting force supplied by the surface of the incline, the normal, . These forces are shown in blue. Since the object slides along the surface of the incline, we need to use the components of its weight, mg, when working problems.
