A force of 25 N is on the end of a 4 meter lever arm turning clockwise. What is the torque?
so CW is neg
so 25*-4=-100Nm
right?
looks good
Yes, you are correct. Since the force is turning clockwise, we assign a negative sign to represent the direction. Using the formula for torque, which is torque = force × lever arm, we can calculate the torque as follows: torque = 25 N × (-4 m) = -100 Nm.
Yes, you are correct. To calculate the torque in this situation, you need to multiply the force applied to the lever arm by the length of the lever arm and the cosine of the angle between the force and the lever arm.
In this case, the force is 25 N and it is applied at the end of a 4-meter lever arm, with a clockwise direction. Since the clockwise direction is considered negative, you can multiply the force (-25 N) by the length of the lever arm (-4 m) to get the torque.
So, -25 N * (-4 m) = 100 Nm.
Therefore, the torque is 100 Nm in the clockwise direction.
