# A crane lowers a 600kg generator by attaching 4 cables to it at an angle of 67° compared to the horizontal. The generator moves at a rate of -2.12m/s². How much tension is on each cable?

##### 1 Answer

#### Explanation:

See figure above.

Let

The vertical upward component of tension in each cable

Total vertical upward component of tension in all 4 cables

The generator is being acted upon by two forces.

1. Weight given by

2. Downward acceleration

As the downward acceleration is in the direction of gravity hence net downward force is given by

Net downward force

Equating the total vertical tension with net downward force we obtain
