Consider the system for lifting a mast, discussed in Chapter 3 and shown again in Figure. The 70-ft-long mast weighs 500 lb. The winch applies a force f = 380 lb to the cable. The mast is supported initially at an angle of θ = 30° and the cable at A is initially horizontal. The equation of motion of the mast is
25,400θ = -17,500 cos θ + 626000/Q sin(1.33 + θ)
Where
Q = ˆš(2020+ 1650 cos (l .33 + θ)) Create and run a Simulink model to solve for and plot θ (t) for θ (t) ‰¤ Ï€/2 rad.
