13–38. The 300-kg bar B, originally at rest, is being towed over a series of small rollers. Determine the force in the cable when t = 5 s, if the motor M is drawing in the cable for a short time at a rate of v = (0.4r²) m/s, where t is in seconds (0 = 1s 6 s). How far does the bar move in 5 s? Neglect the mass of the cable, pulley, and the rollers.

The arm of a starter is held in the "ON" position by means of an eleetromagnet. The torque exerted by the spring is 5 Nm and the effective radius at which the force is exerted is 10 cm. Area of each pole face is 2.5 cm? and each air gap is 0.4 mm. Find the minimum number of ampere-turns (AT) required to keep the arm in the "ON" position.?
If the rod of negligible mass is subjected to a couple moment of M = (30t^2) N⋅⋅m, and the engine of the car supplies a traction force of F = (15t) N to the wheels, where t is in seconds, determine the speed of the car at the instant t = 12.5 s. The car starts from rest. The total weight of the car and rider is 1.5 kN. Neglect the size of the car.
At 714 A.M. on June 30, 1908, a huge explosion occurred above remote central Siberia, at latitude 61 N and longitude 102 E; the fireball thus created was the brightest flash seen by anyone before nuclear weapons. The Tunguska Event, which according to one chance witness “covered an enormous part of the sky,” was probably the explosion of a stony asteroid about 140 m wide. (a) Considering only Earth’s rotation, determine how much later the asteroid would have had to arrive to put the explosion above Helsinki at longitude 25 E. This would have obliterated the city. (b) If the asteroid had, instead, been a metallic asteroid, it could have reached Earth’s surface. How much later would such an asteroid have had to arrive to put the impact in the Atlantic Ocean at longitude 20 W? (The resulting tsunamis would have wiped out coastal civilization on both sides of the Atlantic.)
The velocity of the 8-kg cylinder is 0.3 m∕s at a certaininstant. The mass of the grooved drum is 12 kg, its centroidal radiusof gyration is k = 210 mm, and the radius of its groove isri = 200 mm. The frictional moment at O is a constant3 N∙m. Find the frictional force if final speed is given to be 2.5.
