a hoist has a winding drum 0.9 m effective diameter and a various of gyration of 0.35 m the mass of the drum being 100kg a load

  • Nov 01, 2020 · A hoist is a device used for lifting or lowering a load by means of a drum or lift-wheel around which rope or chain wraps. It may be manually operated, electrically or pneumatically driven and may use chain, fiber or wire rope as its lifting medium. The most familiar form is an elevator, the car of which is raised and lowered by a hoist mechanism.

    The turbine rotor of a ship is of mass 3500 kg. It has a radius of gyration of 0.45 m and a speed of 3000 rpm, clockwise when looking from stern. Determine the gyroscopic couple and its effect upon the ship: [10] Q7) a) b) i) When the ship is steering to the left on a curve of 100 m radius at a speed of 36 km/hr; ii)

  • To do a rough calculation of the force necessary to get it moving, I will use a total lift distance of about 1 m in a time of about 1 s so the speed is roughly v=1 m/s; 500 lb has a mass of about m=227 kg. (I will use SI units, like scientists prefer, and convert back to pounds in the end.)

  • After the collision, the center of mass of the rod has a velocity U, the point mass has a velocity u, and the rod has an angular velocity ω about the center mass. Because the rod is uniform, its moment of inertia about the center of mass is I=ML 2 /12; the angular momentum and kinetic energy of a rigid body are L=I ω and K =½ I ω 2

A cantilever beam 3.8 m long with a mass of 10 kg/m carries a concentrated load of 1000 N at its free end. The other end of the beam is inserted into a wall 0.8 m thick.

  • The gravitational force on a small mass m a distance r from the center of a sphere (and outside the sphere itself) depends on m andthe mass of the sphere, M; the dependence on the distance is 1/r 2, so, for example if you go a distance twice as far away, the force gets 4 times smaller.
