Description
A hoist is used to move material in a facility; the following details apply:The winding drum of the hoist has a mass of 150 kgThe winding drum of the hoist has an outer diameter of 600 mmThe winding drum of the hoist has a radius of gyration of 220 mmThe mass moved by the hoist is 110 kgThe distance moved by the mass is 4·5 mThe frictional resistance at the bearings is 7 NmThe frictional resistance to linear motion is 160 NThe cable used to support the load is considered to be massless.If the hoist is used to lower the mass, while the velocity is increased from 2·0 m/s to 3·5 m/s,determine:(a) The input torque applied.
