A man uses a crowbar of length 2.5 m to raise a load of 75 kgf by putting a sharp edge below the bar at a distance 1 m from his hand. State the kind of lever used and calculate the effort needed.
The mass of a body is 25 kg. What would the weight of the body be in:
(i) Kgf and
(ii) Newton
take, g=10 m/s2
A man uses a crowbar of length 1.5 m to raise a load of 75 kgf by putting a sharp edge below the bar at a distance 1 m from his hand. State the kind of lever and calculate the effort needed.
A body when acted upon by a force of 10 kgf moves to a distac=nce 0.5 m in the direction of force. Find the work done by the force. take 1 kgf = 10 N.
A force of 5 kgf is required to cut a metal sheet. A shear is used for cutting a metal sheet; its blade is 5 cm long while its handle is 10 cm long. What effort is needed to cut a sheet?
