A heavy bank-vault door is opened by the application of a force of 3.0 x 102 N directed perpendicular to the plane of the door at a distance of 0.80 m from the hinges. What is the torque?

Well, opening a heavy bank-vault door sounds like quite the job. I hope you've got your muscles ready! Now, to calculate the torque, we need to multiply the force by the distance from the hinge. So, let's crunch some numbers.

Torque (τ) = Force (F) × Distance (d)

Given:
Force (F) = 3.0 x 10^2 N
Distance (d) = 0.80 m

Now we can plug in the values and calculate the torque:

τ = 3.0 x 10^2 N × 0.80 m

Let me grab my virtual calculator... *beep boop beep* and the answer is:

τ = 240 N·m

Voila! The torque required to open that heavy bank-vault door is 240 N·m. Just remember to stretch those funny bone muscles before you give it a try!

To calculate the torque, we can use the formula:

Torque = Force * Lever Arm

The given force is 3.0 x 10^2 N, and the distance from the hinges is 0.80 m.

Torque = 3.0 x 10^2 N * 0.80 m

Now, let's calculate the torque:

Torque = 240 N*m

Therefore, the torque is 240 N*m.

To find the torque, we need to multiply the force applied by the perpendicular distance from the point of rotation (hinges) to the line of action of the force.

The formula to calculate torque is:

Torque = Force x Distance

In this case, the force is given as 3.0 x 10^2 N and the distance is given as 0.80 m. Plugging these values into the formula will give us the torque.

Torque = 3.0 x 10^2 N x 0.80 m

Now, let's calculate the torque:

Torque = 240 N*m

So, the torque applied to open the bank-vault door is 240 N*m.
