3 digits behind comma From the given figure, F = 100 N. • Draw the FBD 1000 mm • Draw the action line of all forces that intersect in one point directly in the figure. Determine: 60° a) Force at smooth roll B b) Force at pin A Analytical solution. B 125 mm

Solve the problem. A 11-in. connecting rod in an engine connects the wrist pin of a piston at point A to the end of a second rod at point on the crankshaft. As the piston moves forward and back, the crankshaft is turned counterclockwise around point C. The stroke length of the engine is the distance that the piston travels (one way) with its cylinder. If the stroke length is 4 in., and the engine turns at 600 rpm, write a model representing the distance d (in inches) from A to the center of the crankshaft Cas a function of time t (in minutes). Assume that at t = 0, the piston is at its farthest point from the crankshaft. B B C C B A A stroke length
