An offset crank-connecting rod mechanism is given in the figure below. P12 and P14 are external forces that act on the points shown on the mechanism. Ignoring the weights, the angle θ3 is the input for the situation;
a1 = 20 mm, a2 = 100 mm, a3 = 250 mm, b3 = 120 mm, θ3 = 30°, θ12 = 300°, P12 = 30 N, and P14 = 10 N. Find numerically the values of θ13 and S14.
(Ax = 0, Ay = 0).
