VAN NOSTEAND'S ENGINEERING MAGAZINE. '237 Let us now observe the effect produced Construct the triangle of forces, d e f, by altering the slope, A B, to A D. as before, making d f — C D, to represent the weight of A C I). The angle, e df, is now greater than the angle, a c b, Fig. 1. … moving from the position Ax to A2 the angle, 6 A p, of the triangle of forces that the slope of the plane varies, and will increase to cA} in the same ratio the side A b will decrease to A c in the that Ct decreases to C2. "We are thus enabled to make a diagram illustrating the successive changes…
