Test4: Mechanical system calculation quiz

What is the mechanical advantage of a gear system determined by?

• Gear size

• Gear ratio

• Gear speed

• Gear material

If the driving gear has 10 teeth and the driven gear has 30 teeth, what is the gear ratio?

• 1:3

• 3:1

• 1:2

• 2:1

If the driving gear applies a torque of 50 N·m, what is the torque on the driven gear with a gear ratio of 3:1?

• 150 N·m

• 50 N·m

• 100 N·m

• 25 N·m

What is the formula for calculating Mechanical Advantage (MA) in a lever?

• MA = Load Arm / Effort Arm

• MA = Effort Arm / Load Arm

• MA = Load Arm + Effort Arm

• MA = Load Arm - Effort Arm

If a lever has an effort arm of 5 meters and a load arm of 1 meter, what is the mechanical advantage (MA)?

• 1

• 2

• 5

• 10

If the load of the system weighs 20N and the mechanical advantage is 5, how much effort is needed?

• 4N

• 5N

• 10N

• 20N

What is the mechanical advantage (MA) if there are 5 supporting ropes in a block and tackle system?

• 3

• 4

• 5

• 6

If the load of the system weighs 500 N and the mechanical advantage is 5, what effort is needed to lift it?

• 100 N

• 200 N

• 250 N

• 300 N

What is the formula for calculating the mechanical advantage (MA) of a wheel and axle system?

• MA = Radius of the Axle / Radius of the Wheel

• MA = Radius of the Wheel / Radius of the Axle

• MA = Radius of the Wheel + Radius of the Axle

• MA = Radius of the Axle - Radius of the Wheel

If the radius of the wheel is 40 cm and the radius of the axle is 5 cm, what is the mechanical advantage?

• 5

• 8

• 10

• 12
