To calculate tension in an elevator cable, you can use the formula T = m*a, where T is the tension, m is the mass of the elevator and its occupants, and a is the acceleration due to gravity. Make sure to consider any additional forces or factors that may affect the tension in the cable.
What else can I help you with?
How the tension can be greater than gravity yet the elevator is moving downwards?
The tension can be greater than gravity when the elevator is accelerating downwards, causing a net force that exceeds the force of gravity acting on the elevator. This creates a situation where the tension in the elevator cable is greater than the force of gravity, allowing the elevator to move downwards.
What are the key components and forces involved in an elevator free body diagram?
In an elevator free body diagram, the key components are the elevator itself, the tension in the supporting cable, the force of gravity acting on the elevator and its occupants, and the normal force exerted by the floor of the elevator. The forces involved include the tension in the cable, the force of gravity pulling the elevator down, and the normal force pushing the elevator and its occupants up.
Why might an elevator cable break during acceleration when lifting a lighter load than it normally supports at rest or at constant velocity?
When lifting a lighter load during acceleration, the tension in the elevator cable may increase more rapidly than when the elevator is stationary or moving at a constant velocity. This sudden increase in tension can exceed the cable's maximum load capacity, causing it to break. Additionally, if the cable has been weakened due to wear and tear, it may be more susceptible to breaking under the increased tension.
What are the 5 examples of tension force?
Tension force in a rope or string holding an object suspended. Tension force in the cable of a cable car or elevator carrying passengers up or down. Tension force in the strings of a musical instrument like a guitar or violin. Tension force in a spring being stretched or compressed. Tension force in the cables supporting a bridge or a flagpole.
The cable supporting a 2125 kg elevator has a maximum strength of 21750 N. What maximum upward accerleration can it give the elevator without breaking?
Using Newton's second law (F = ma), the maximum upward acceleration the elevator can have without breaking the cable is 10.23 m/s^2. This is calculated by dividing the maximum tension in the cable (21750 N) by the mass of the elevator (2125 kg).

What forces are acting upon an elevator when going up?
When an elevator is going up, the main forces acting upon it are the gravitational force pulling it downward and the tension in the elevator cable pulling it upward. Additionally, there may be a frictional force acting against the motion, depending on the smoothness of the elevator ride.
What is the solution to the physics elevator problem?
The solution to the physics elevator problem involves calculating the net force acting on the elevator and using Newton's second law to determine the acceleration of the elevator. By considering the forces of gravity, tension in the cable, and the normal force, one can find the acceleration and ultimately solve the problem.

How does the Otis elevator brake work?
The Otis elevator brake was built to suspend the car safely in the shaft if an elevator cable snapped. Otis started experimenting on how to make the brake by placing a wagon spring above the hoist platform. Then, he attached a ratchet bar to the guide rails on the sides of the hoistway. The lifting rope was next fastened to the wagon spring so that the weight of the hoist platform held just enough tension on the spring to keep it from touching the ratchet bars. However, if the cable snapped, the tension would be released from the spring. It would then immediately engage the ratchets, preventing the platform from falling.
