# Power Transmission Chapter 1 Flashcards

What is Friction?

Resistance to movement.

What is Force?

A push or pull on an object.

What force makes the body move?

Net force.

Friction work’s opposite of force.

True

Torque is defined as?

Rotational force.

The formula for Torque is?

T=FxD (torque equals rotational force times distance)

Formula for diameter is?

Radius x 2 (2 x R)

Formula for circumference is?

Pie x D (pie x diameter)

The area of a circle formula is?

.7854 x D2 or pie x r2

The definition of RPM is?

Rate of rotation

What is the definition of Power?

Rate at which work is done.

Formula for work? (Power)

Work done = Linear force x Distance

Work is defined as?

Linear force.

What is the formula for horse power? (FTPDS)

HP = Torque x rpm divided by 5252.

What is the most important formula in power transmission?

Horsepower.
