A see-saw is 25 feet long with a fulcrum in the middle of the board. If a 60 lb. child sits three feet from the fulcrum, what is
My name is Ann [436]

Answer:

14.4 lb

Step-by-step explanation:

In a see-saw in equilibrium, the torque generated by one side needs to be the same generated in the other side. The torque is calculated by the product between the mass and the distance to the center of the see-saw.

The torque generated by the child is:

T1 = 60 * 3 = 180 lb*feet

So, the torque generated by the weight needs to be higher than T1 in order to lift the child.

The lowest mass is calculated when the mass is in the maximum distance, that is, 12.5 feet from the center.

So, we have that:

T2 = 180 = mass * 12.5

mass = 180/12.5 = 14.4 lb

So the lowest weight is 14.4 lb

A tree trunk is pulled with a force of 3200 pounds by a truck’s cable that makes an angle of 25° with the horizontal. What is th
mr_godi [17]

Answer:

The vertical component of the force correct to the nearest pound Is

1352 pound

Step-by-step explanation:

Kindly find attached for your reference

This problem bothers on the topic of work energy and power

Given data

Applied force = 3200 pounds

Angle of application = 25°

We know that the horizontal force =

F= 3200cos 25°

Hence the vertical component of this force = F= 3200sin 25

=3200*0.42261

= 1352.352

to the nearest pound

F = 1352pound
