Question: A machine part consists of a thin 44.9-cm-long bar with small 1.96-kg masses fastened by screws to its ends. The screws can support a maximum force of 75.1N without pulling out. This bar rotates about an axis perpendicular to it at its center.Using the result of part B, what is the greatest speed the masses can have without pulling a screw?
A 770 kg car moving at 21 m/s brakes to a stop. The brakes contain about 15 kg of iron, which absorbs the energy. What is the increase in temperature of the brakes.
The leg and the cast in Fig 4.20 below weigh 220 N (w1). Determine the weight w2 and the angle α needed so that no force is exerted on the hip joint by the leg plus the cast.
Why does the tilt of the Earth cause the seasons? It seems to me like the distance from the Earth to the Sun should cause the seasons.
A proton at the origin is moving in the positive x direction at 3.7x10^4 m/s, and at that moment the electric field is 7.9x10^3 N/C, What is the electromagnetic force on the proton at that moment
A charge of -1.0 µC is located at the origin, a second charge of 3.4 µC is located at x = 0, y = 0.1 m, and a third charge of 5 µC is located at x = 0.2 m, y = 0. Find the forces that act on each of the three charges. q = -1.0 µC
