Exercise 26: Consider a uniform and homogeneous rod of length AB = 2m, and mass m = 2kg. This rod is free to rotate without friction around a horizontal axis through a point O of the rod so that AO = 20 cm while a load of mass M is suspended at a point C so that BC = 20cm. By means of a horizontal string BD, the rod is kept in equilibrium, as shown in the adjacent figure so that AB makes an angle a with the vertical, where sina = 0.6 and cosa -= 0.8 (Take g = 10m/s³) 1. Make an inventory of forces acting on the rod C Wall D B M AB. 2. Determine the value of mass M, knowing that the tension in the horizontal string BD is 100N. 3. Determine the magnitude of the reaction of the axis at O and then deduce its direction relative the horizontal.

A load of mass 230 kg is lifted by means of a rope which is wound several times round a drum andwhich then supports a balance mass of 140 kg. As the load rises, the balance mass falls. The drum hasa diameter of 1.2 m and a radius of gyration of 530 mm and its mass is 70 kg. The frictional resistanceto the movement of the load is 110 N, and that to the movement of the balance mass 90 N. Thefrictional torque on the drum shaft is 80 N-m.Find the torque required on the drum, and also the power required, at the instant when the load has anupward velocity of 2.5 m/s and an upward acceleration of 1.2 m/s2.
From the step ladder shown in the figure, sides AC and CE are each 2.44 m long and hinged at point C. Bar BD is a tie-rod 0.762 m long, halfway up. A man weighing 845 N climbs 1.8 m along the ladder. Assuming the floor is frictionless and neglecting the mass of the ladder, find the tension (in N) in the tie-rod.
The following figure shows a 4 m bar attached to the wall through a hinge that rotates freely, but is tied to the wall at its other end so that the system is in equilibrium. If the bar weighs 40 N and the tension in the rope is 20 N, find the angle of inclination θ (theta) that the bar makes with the x-axis and the magnitude of the reaction force at the hinge.
