Question

Determine the torque caused by the cable pulling horizontally on the inclined drawbridge. The force the cable exerts on the bridge is 5000N and the bridge length is 8 m.

Answer 1

Answer:

$\tau=20000\ Nm$

Explanation:

Given that,

The force the cable exerts on the bridge is 5000N

The length of the bridge is 8 m

We need to find the torque caused by the cable pulling horizontally on the inclined draw bridge. The torque acting on it is given by :

$\tau=Fr$

Putting all the values,

$\tau=5000\ N\times 8\ m\\\\=20000\ Nm$

So, the required torque is 20000 Nm.
