will turn at equal speed.    Will turn at different speed.

Will turn faster.    will turn slower.

2.    In meshed gears to work out how fast one is turning with respect to the other you need to................?

Count the teeth.    See the direction of motion.

See the size.    Note the speed of each gear.

3.    Gear A turns clockwise at a constant speed of 30 rpm, how does gear B turn, if the number of teeth in gear A are 8 and in gear B are 24?

Anti clockwise 30 rpm    Clockwise 10 rpm

Clockwise 5 rpm    Anti clockwise 10 rpm

4.    If Lower bar moves left at a constant speed, how does upper bar move?

Left, Slower than lower bar    Right, at the same speed as lower bar

Left, Faster than lower bar    Left, at the same speed as lower bar

5.    Gear A turns clockwise at a constant speed of 10 rpm, how does gear B turn, if the number of teeth in each gear are equal?

Anti clockwise 10 rpm    Clockwise 20 rpm
