The screw jack experiment determines the mechanical advantage, velocity ratio and efficiency of a screw jack, and shows why it

The worm and worm wheel experiment determines the velocity ratio, mechanical advantage and efficiency of a worm-gear lifting machine, which

The journal bearing apparatus experiment studies how a rotating shaft is supported on a film of oil, by measuring the

The epicyclic gear train experiment determines the velocity ratio and holding torque of a planetary gear train and verifies that

In an impulse turbine all the fluid’s pressure energy is converted into kinetic energy in a fixed nozzle before the

The core difference in an open loop vs closed loop control system is feedback: an open loop system applies a

Static vs dynamic balancing differ in the conditions they satisfy: a rotor is in static balance when the resultant of

The core torque vs power difference is this: torque is the rotational (twisting) force a shaft delivers, measured in newton-metres

A strain gauge is a thin sensor whose electrical resistance changes when it is stretched or compressed, letting you measure
