When u=1-a, equation (2) is called Bernoulli's equation and can be solved in closed form. Solve equation (2) when K=12, a=3/4, µ=1/4, Wmax =81 (ounces) and W(0) =1 (ounces). Determine the lim W (t). The constants are given for t measured in months.arrow_forward(b) Figure 1(b) shows the 10 kg rod AB which is constrained so that its end of slider block B moves along the fixed guide. The rod is initially at rest when 0 = 0°. If the slider block A is acted upon by a vertical force P = (90M) N; Note; Use your last three digit of matrix number to determine the value of force P as follows; Example of matrix number, CD190002 M = (0+0+2) = 2 Therefore, P = 90M N, = 90+2 = 92 N Draw kinematic diagram of the rod at 0 = 0° and 0 = 30° respectively.
