A 800N man is playing on a seesaw with son who has a weight of 200N. If the child is sitting 3 meters away, how far will the man have to sit to balance the seesaw?
a)
0.75m
b)
3m
c)
1.5m
d)
1m
11.
A seesaw with mass x is perfectly balanced with a fulcrum in the center. If mass x changes uniformly does the net torque change?
a)
Yes, because the Gravitational force increases with more mass, and torque is related to Force
b)
No, because the net torque is still zero despite increases in one of the individual components.
c)
No, because it is balanced that means net torque is zero, a uniform increase in weight keeps it balanced keeping net torque at zero
d)
Yes, any increase in weight will increase torque
12.
What is the distance the masses on the right of the fulcrum need to be to balance with the two masses on the left?
a)
.65 m
b)
.56 m
c)
.79 m
d)
.39 m
13.
A construction worker is worried about applying too much torque to a bolt using his wrench. What could he do to reduce his torque on the bolt?
a)
Increase the length of the wrench
b)
Increase the force on wrench
c)
Reduce the length of the wrench
d)
Reduce the friction between the bolt and wrench
14.
A state of equilibrium is also seen below. Each of the cars weighs the same 9800 N. Despite the fact that there is only one car on the left-hand side that is 9 m from the fulcrum, the torques balance because, the cars on the right-hand side, are ____meters from the fulcrum.
a)
4.5 m
b)
3 m
c)
1 m
d)
2 m
15.
