Torques(Equilibrium of Solid Objects) Homework Problem - James Bond

In summary, James Bond and Dr. No engaged in a fight on a board over a pool. Dr. No pulls out his weapon, but Bond quickly calculates the torques and jumps off the board, leaving Dr. No behind. Using the given information, it can be determined that Bond is safe and does not fall into the pool. This problem is similar to another one involving torques and a pivot on the edge of a building.

Homework Statement


James Bond and Dr. No are engaged in fisticuffs on a board overhanging a pool. Dr. No now pulls out his weapon. oh no!. Bond is in trouble again. Bond quickly calculates the torques and leaps off the left end of the board leaving Dr. No on the right. Is Bond safe? That is, does no feed the fish? Hint, put the pivot on the edge of the building.
L of the board = 18 meters
Mass of board = 45 kg
Dr. No = 60 kg

What is the definition of torque?

Torque is a measure of how effectively a force causes rotation around an axis. It is calculated by multiplying the force applied by the distance from the axis of rotation.

How is torque related to equilibrium?

In order for an object to be in equilibrium, the sum of all torques acting on it must be zero. This means that the clockwise torques must be equal to the counterclockwise torques.

How does James Bond use torque in his missions?

James Bond often uses torque to his advantage in various situations. For example, he may use a lever or a pulley to apply torque to a door or a safe in order to open it.

What is the difference between positive and negative torque?

Positive torque causes an object to rotate in a counterclockwise direction, while negative torque causes it to rotate in a clockwise direction. The direction of torque depends on the direction in which the force is applied.

How do you calculate torque in a real-world scenario?

To calculate torque in a real-world scenario, you need to identify the force acting on the object, the distance from the axis of rotation, and the angle between the force and the lever arm. Then, you can use the formula Torque = Force x Distance x sin(theta) to calculate the torque.
