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.

Working out a ramp, roof pitch or the slope to a drain from two measurements.

Roof pitches, ramps, braces and setting out any right-angle triangle.

Digging a hole the right width makes the job ten times quicker, and the post is stronger. See Setting Fence Posts.

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.

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.

For land drainage, roof pitch, silage clamp faces, ramps, and whether a load will get up the yard. A 1 in 10 slope is 10%.

Why a ramp needs enough grip, why oil makes a bolt easier to undo, and why a ladder needs its feet on level ground.

Set the height of the first step from the finished floor and the landing, then work down. See Building A Step.

The measure of the whole system - rams, condition, feed, scanning and lambing. It is the number to write down every year.

The energy stored by lifting something. It is why a raised bale or a full water tank is dangerous, and why a ramp gains you the power to lift a load higher.

The force needed to move a mass. The tractor pulling a trailer, the ramp lifting a load, a horse pulling a plough. Double the mass and you double the force, for the same acceleration.
