A flexible chain weighing 40.0 N hangs between two hooks located at the same height (Fig. P12.17). At each hook, the tangent to
the chain makes an angle θ =42.0° with the horizontal. Find (a) the magnitude of the force each hook exerts on the chain.
1 answer:
The magnitude of the force each hook exerts on the chain is 22.2N.
<h3>Solution:</h3>
Horizontal force on one half of the chain
cos 42° =
sin 42° = 20
= 29.9N
Now,
= 22.2N
