  1. Horizontal Pulley with Friction. Application of Newton's second law to a horizontal pulley. Note that the tension in the rope is NOT equal to the weight of the hanging mass except in the special case of zero acceleration. Given a mass of kg on a horizontal table.

  2. Each object will have its own set of forces acting on it, including gravitational forces, tension forces from the ropes or chains, and frictional forces. By creating a separate diagram for each object, it becomes easier to analyze and understand the forces at play.

  3. A pulley is a simple machine that consists of a wheel with a groove in its rim and a rope or chain that runs along the groove. It is used to change the direction or alter the amount of force needed to lift or move an object. Pulleys are commonly used in various applications, such as elevators, cranes, and well systems.

  4. Find the force of friction if (a) \(\vec{P}\) = 20.0 N, (b) \(\vec{P}\) = 30.0 N, (c) \(\vec{P}\) = 120.0 N, and (d) \(\vec{P}\) = 180.0 N. Figure \(\PageIndex{4}\): (a) A crate on a horizontal surface is pushed with a force \(\vec{P}\).

  5. Find the frictional force on the crate when the truck is accelerating forward relative to the ground at (a) 2.00 m/s 2, and (b) 5.00 m/s 2.

  6. 11 cze 2023 · A pulley is a wheel like device that rotates as a string passes over it allowing motion of any particles attached to the string; Pulleys allow a (inextensible) string to change its orientation; In A level mathematical models, pulleys will always be smooth and light, so there is no friction involved at the pulley and its mass is negligible

  7. Find the frictional force on the crate when the truck is accelerating forward relative to the ground at (a) 2.00 m/s 2, and (b) 5.00 m/s 2. Figure \(\PageIndex{5}\): (a) A crate rests on the bed of the truck that is accelerating forward.
