The type of mechanical motion that involves moving in a straight line is called:

• linear

• reciprocating

• oscillating

• tangential

Rotary motion is defined as:

• Moving back and forth

• rotating around an axis

• rotating around a linear plane

• moving in a straight line

The formula for calculating the AMA of a lever is

• Distance of effort divided by distance of resistance

• Distance of resistance divided by distance of effort

• Input force divided by output force

• none of these

Ideal mechanical advantage is calculated using _______

• forces

• distances

• newtons

• weights

The formula for the actual mechanical advantage of a wheel and axle is:

• Output force divided by input force

• input force divided by output force

• Radius of Wheel divided by the radius of the axle

• radius of the axle divided by the radius of the wheel

The mechanical advantage of a wheel and axle, when input is put into the axle, is:

• it depends on forces involved

• less than 1

• greater than 1

• 1

The IMA of a ramp is solved by
