Q2/ The bumper springs of a railway carriage are to be made of rectangular section wire.The ratio of the longer side of the wire to its shorter side is 1.5, and the ratio of meandiameter of spring to the longer side of wire is nearly equal to 6. Three such springsare required to bring to rest a carriage weighing 25 kN moving with a velocity of75 m/min with a maximum deflection of 200 mm. Determine the sides of therectangular section of the wire and the mean diameter of coils when the shorter side isparallel to the axis of the spring. The allowable shear stress is not to exceed 300 MPaand G = 84 kN/mm².Q6/ A belical

The force P applied to the brake handle enables the band brake to reduce the angular speed of a rotating drum. If the tensile strength of the band is 3800 lb, find the maximum safe value of P and the corresponding braking torque acting on the drum. Assume that the drum is rotating clockwise.
Draw the FBD for the bar described in Prob. 5.1 if the bar is homogeneous of mass 50 kg. Count the unknowns.
8. 2) Rods AB and BC are linked at Band have weights of 18 lb and 37 lb, respectively. The 8-lb collar C, which is connected to BC and the spring, slides freely along the smooth vertical guide. The lengths of the rods are 4 = 1.4 ft and 2 = 2.9 ft. If the system is released from rest when 0 = 0°, determine the magnitude of the angular velocity (in rad/s) of rod BC when 0 = 90°. The attached spring has spring constant k = 20 Ib/ft, and is unstretched when 0 = 0°. Please pay attention: the numbers may change since they are randomized.

4. When only conservative forces are acting on a system, we can use the conservation of energy theorem to solve a problem. Recall from particle kinetics: T₁ + V₁ = T2 + V2, where V is potential energy (due to both gravitational and elastic forces: V₂ = Wyc and Ve= + ½ ks², respectively). The 30-kg rod is released from rest when 0 = 45°. The spring is unstretched when 0 = 45°. Using conservation of energy theorem, determine the angular velocity of the rod when 0 = 0°.

5. A former student of mechanics wishes to weigh himself but has access only to a scale A with capacity limited to 400 N and a small 80 N spring dynamometer B. With the rig shown, he discovers that when he exerts a pull on the rope so that B registers 76 N, the scale A reads 268 N. What is his mass m? Also, what range of weight can be measured with this system? A B
Block A rests on a horizontal tabletop. A light horizontal rope is attached to it and passes over a pulley, and block B is suspended from the free end of the rope. The light rope that connects the two blocks does not slip over the surface of the pulley (radius 0.080 m) because the pulley rotates on a frictionless axle. The horizontal surface on which block A (mass 2.50 kg) moves is frictionless. The system is released from rest, and block B (mass 5.00 kg) moves downward 1.80 m in 2.00 s. A)What is the tension force that the rope exerts on block B ?B)What is the tension force that the rope exerts on block A ?
