# A wrench with a length of #24 cm# is being used to unscrew a #3 cm# bolt. If a torque of #88 Nm# is needed to overcome the friction keeping the bolt in place, what is the minimum torque that must be applied to the wrench to unscrew the bolt?

You must apply a minimum torque of 88 Nm to loosen the bolt.

The question specifies that in order to loosen the bolt, you must apply a minimum torque of 88 Nm. It is not possible to determine how much less torque is needed in order to fully remove the bolt once it has been loosened.

Hope this is helpful, Steve.

To calculate the minimum torque required to unscrew the bolt, you can use the equation for torque, which is torque = force * lever arm. Rearrange the equation to solve for force: force = torque / lever arm. Then, substitute the given values into the equation and solve for force. Once you have the force, you can use it to calculate the torque needed to unscrew the bolt by multiplying the force by the lever arm of the wrench. Finally, plug in the values and calculate the minimum torque required to unscrew the bolt.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.

- How much work does it take to raise a #41 kg # weight #5 m #?
- A force field is described by #<F_x,F_y,F_z> = < x , z, y > #. Is this force field conservative?
- A spring with a constant of #3 (kg)/s^2# is lying on the ground with one end attached to a wall. An object with a mass of #3 kg# and speed of #5 m/s# collides with and compresses the spring until it stops moving. How much will the spring compress?
- An object with a mass of #15 kg# is hanging from an axle with a radius of #24 m#. If the wheel attached to the axle has a radius of #15 m#, how much force must be applied to the wheel to keep the object from falling?
- A balanced lever has two weights on it, the first with mass #9 kg # and the second with mass #72 kg#. If the first weight is # 16 m# from the fulcrum, how far is the second weight from the fulcrum?
