Calculating Tension in Cable Winch BD - Drawing Included

In summary, the problem involves finding the tension in cable winch BD based on a given drawing. The mass fixed to the other end of the pulley is 200 kg. The attempt at a solution involved calculating the tension based on the mass and acceleration, but there is uncertainty about the forces and whether the mass is accelerating. Further clarification is needed to determine the tension in the cable.

Homework Equations


The mass fixed to the other end of the pulley is 200 kg.

The Attempt at a Solution


I was under the impression that if one side of the pulley pulled down with 1960 N (200 kg * 9.81 ms^-2) then the tension in the winch would be the same as well.
Can anyone shed some light on this?

Is the mass is accelerating? So the forces on the 200 kg mass sum to _____? What are the forces? If there was any difference in the tension of the rope along the rope, what would have to occur?

Your understanding is correct. The tension in cable winch BD will be equal to the force applied on the other side of the pulley, which in this case is 1960 N. This is due to the principle of conservation of energy, which states that the total energy in a system remains constant. In this case, the energy is being transferred from the force applied on one side of the pulley to the tension in the cable on the other side. Therefore, the tension in cable winch BD will be 1960 N.
 

1. What is the formula for calculating tension in a cable winch?

The formula for calculating tension in a cable winch is T = (W x L)/2. Where T represents tension, W represents the weight being lifted, and L represents the length of the cable being used.

2. How do I determine the weight to use in the formula for tension calculation?

The weight used in the formula for tension calculation should be the total weight of the object being lifted, including any additional weight from attachments or accessories.

3. Can the length of the cable affect the tension in a cable winch?

Yes, the length of the cable can affect the tension in a cable winch. The longer the cable, the more tension is required to lift the same weight due to the added weight of the cable itself.

4. Is there a maximum weight that can be lifted using a cable winch?

Yes, there is a maximum weight that can be lifted using a cable winch. This weight will vary depending on the strength and capabilities of the specific winch being used. It is important to check the winch's specifications and limitations before attempting to lift a heavy load.

5. What safety precautions should be taken when using a cable winch?

When using a cable winch, it is important to always follow safety protocols and guidelines. This includes wearing appropriate personal protective equipment, checking the winch and cable for any signs of damage before use, and ensuring that the weight being lifted does not exceed the winch's capacity. It is also important to never stand directly under the winch or in the path of the cable in case of a malfunction.
