A crowbar lever , with a 3 inch long nail remover connected to a 20inch handle. If you push down on the handle end with a force of 40 N, what force is available to remove a nail? HINT: a Crowbar isnt all that different from a seesaw, except the pivot is far off center.

40*20=F*3

So just multiply the 40 and 20 then divide by 3? what equation is this. could you write it out without numbers

To find the force available to remove a nail using a crowbar lever, we can use the concept of torque. Torque is the product of the force applied and the distance from the pivot point (fulcrum). In this case, the handle end of the crowbar serves as a lever, and the nail remover acts as the pivot point.

First, let's calculate the torque exerted by the force applied to the handle end of the crowbar. The torque equation is:

Torque = Force × Distance

The distance from the handle end to the pivot (fulcrum) is 20 inches. So, the torque exerted by the force applied at the handle end is:

Torque = 40 N × 20 inches

Now, we need to determine the distance from the pivot to the point where the nail remover is connected. The length of the nail remover is given as 3 inches. Since the pivot point is far off-center, the distance from the pivot to the nail remover can be considered negligible. Therefore, we can assume that the distance is effectively 0 inches for the calculation of torque at the nail remover end.

Now, the torque exerted at the nail remover end of the crowbar is equal to the torque exerted by the force applied at the handle end. Therefore, the force available to remove the nail can be calculated using the torque equation:

Force (at nail remover) = Torque / Distance (from nail remover to pivot)

Since the distance in this case is effectively 0 inches, the force available to remove the nail would be:

Force (at nail remover) = Torque / 0 inches

However, dividing by zero is undefined. Thus, we cannot determine the force available to remove the nail based on the given information.

In summary, the force available to remove the nail cannot be determined without additional information such as the distance between the pivot point and the point where the force is applied at the nail remover end of the crowbar lever.
