Calculation of the Force Exerted by the Tractor on the Middle of the Bridge

To calculate the force exerted by the tractor on the middle of the bridge, we need to consider the centripetal force acting on the tractor as it moves along the curved path of the bridge. The centripetal force is responsible for keeping the tractor moving in a circular path.

The formula for centripetal force is:

F = (m * v^2) / r

Where: - F is the centripetal force - m is the mass of the tractor - v is the velocity of the tractor - r is the radius of the curved path (in this case, the radius of the bridge)

Given the following information: - Mass of the tractor (m): 10 tons (10,000 kg) - Velocity of the tractor (v): 36 km/h (10 m/s) - Radius of the bridge (r): 200 meters

Let's calculate the force exerted by the tractor on the middle of the bridge.

Step 1: Convert the velocity from km/h to m/s: - 36 km/h = 36,000 m/3600 s = 10 m/s

Step 2: Substitute the values into the formula for centripetal force: - F = (10,000 kg * (10 m/s)^2) / 200 m

Step 3: Calculate the centripetal force: - F = (10,000 kg * 100 m^2/s^2) / 200 m - F = 5,000,000 N

Therefore, the force exerted by the tractor on the middle of the bridge is 5,000,000 Newtons.
