Answer:
[tex]\tau=20000\ Nm[/tex]
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 :
[tex]\tau=Fr[/tex]
Putting all the values,
[tex]\tau=5000\ N\times 8\ m\\\\=20000\ Nm[/tex]
So, the required torque is 20000 Nm.
