Chapter: 05. Simple Machine

⁠

A _ _ _ _ _ _ _ _ _ _ _ _ _ _ is an arrangement in which a wheel is attached to a rod, called the axle.

In a lever of the first order, the _ _ _ _ _ _ _ _ _ _ _ _ _ _ is between the load and the effort.

The windings on a screw are called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Moving parts of machines should be _ _ _ _ _ _ _ _ _ _ _ _ _ _ using oil to reduce friction.

A _ _ _ _ _ _ _ _ _ _ _ _ _ _ is used to lift a car while changing its wheels.

A _ _ _ _ _ _ _ _ _ _ _ _ _ _ is an example of a lever of the second order.

Ideally, the efficiency of a machine would be _ _ _ _ _ _ _ _ _ _ _ _ _ _.

A simple machine that consists of a wheel with a grooved rim, over which a rope or chain can be passed, is called a _ _ _ _ _ _ _ _ _ _ _ _ _ _.

A screw is an inclined plane wrapped around a _ _ _ _ _ _ _ _ _ _ _ _ _ _.

The external force applied to lift or move the load is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

A _ _ _ _ _ _ _ _ _ _ _ _ _ _ is formed when two inclined planes are attached back to back.

Mechanical advantage is given by the ratio of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ to the _ _ _ _ _ _ _ _ _ _ _ _ _ _.

Machines help us to apply force at some _ _ _ _ _ _ _ _ _ _ _ _ _ _ point and to produce its effect at some other point.

An inclined plane is simply a plane surface that is _ _ _ _ _ _ _ _ _ _ _ _ _ _ to the horizontal.

A single fixed pulley helps us to change the _ _ _ _ _ _ _ _ _ _ _ _ _ _ of the effort.

In levers of the third order, the mechanical advantage is always _ _ _ _ _ _ _ _ _ _ _ _ _ _ than 1.

In a single movable pulley, a load can be lifted which is _ _ _ _ _ _ _ _ _ _ _ _ _ _ as much as our effort.

Machines help to do the work with _ _ _ _ _ _ _ _ _ _ _ _ _ _ effort.

A fixed point about which the machine turns while doing mechanical work is called _ _ _ _ _ _ _ _ _ _ _ _ _ _.

For a balanced lever, Load × Load arm = _ _ _ _ _ _ _ _ _ _ _ _ _ _ × Effort arm.

The ratio of the output energy to the input energy determines the _ _ _ _ _ _ _ _ _ _ _ _ _ _ of the machine.

A wheel and axle consists of two cylinders of _ _ _ _ _ _ _ _ _ _ _ _ _ _ diameters joined together.
