A man uses a crowbar of length 1.5m to raise a load of 75 kgf by putting a sharp edge below the bar at a distance of 1m from his hand. The load is at the opposite end of the effort. Calculate (i) load arm (ii) effort arm (iii) mechanical advantage and (iv) the effort needed.
A boy uses a single movable pulley to lift a load of 50kgf to some height. Another boy uses a single fixed pulley to lift the same load to the same height. The ratio of efforts on single movable pulley to efforts on single fixed pulley is,
