Pulleys

Pulley with fixed axis of rotation is called

• combination pulley

• single fixed pulley

• block and tackle system

• single movable pulley

In practical, the velocity ratio of a single fixed pulley is

• = 1

• < 1

• >1

• None of the above

A single pulley with MA > 1 is:

• Single fixed pulley

• fixed and movable pulley

• Single movable pulley

• Block and tackle system

A single movable pulley is a

• speed multiplier

• force multiplier

Ideal Mechanical advantage of a single movable pulley is

• 1

• 2

• 0.5

• 1.5

Single movable pulley along with a fixed pulley is used as:

• speed multiplier

• force multiplier

• force multiplier and change of direction of force

• speed multiplier and change of direction of force
