What is torque?

Back

Torque is a measure of the rotational force applied to an object, calculated as the product of the force and the distance from the pivot point (Torque = Force x Distance).

Front

What happens when the torques from the load and force applied are balanced?

Back

When the torques are balanced, the weight of the load and the force applied are equal or close to equal.

Front

How does the position of the pivot affect the force needed to lift a load?

Back

Moving the pivot closer to the effort force increases the force needed to lift the load.

Front

What is the relationship between force, distance, and torque?

Back

Torque is directly proportional to both the force applied and the distance from the pivot point.

Front

What is the formula for calculating torque?

Back

Torque (τ) = Force (F) x Distance (d) from the pivot.

Front

In a lever system, what is the effect of increasing the distance from the pivot to the applied force?

Back

Increasing the distance reduces the amount of force needed to lift the load.

Front

What is the role of a car's transmission in relation to torque?

Back

A car's transmission adjusts the torque and speed from the engine to deliver appropriate torque and speed to the wheels.

Front

What is a lever?

Back

A lever is a simple machine that consists of a rigid bar that pivots around a fixed point (the fulcrum) to lift or move loads.

Front

What is the fulcrum in a lever system?

Back

The fulcrum is the pivot point around which the lever rotates.

Front

What is mechanical advantage in the context of levers?

Back

Mechanical advantage is the ratio of the output force produced by a machine to the input force applied, indicating how much a machine amplifies force.
