Ramps, loading ramps, the screw jack, the post hole auger and the cider press. Work in always equals work out, so a gentle ramp just means more walking.
The jack, the brake press, the loader bucket and the post hole rammers. A 10 cm piston moved with 100 N will lift 1,000 kg on a 1 m piston.
Friction and heat are the losses. A lower efficiency means more fuel, more electricity and more heat to shift away.
A lever, a block and tackle, a ramp, a screw jack. You trade distance for force, and no machine beats 100% efficiency. A ramp 4 m long and 1 m high has a theoretical advantage of 4.
The whole of the spanner, the jack, the pump handle and the gate hinge. Torque depends on where you put your hand, not on how hard you pull. A 100 N push at 0.3 m gives 30 N m.
