Question

A vehicle ia crossing a vertical convex bridge. The force exerted by vehicle
on mid-point of the bridge with convex curvature (moving at constant
speed) will be​

Answer 1

HELLO DEAR,

ANSWER:-

The force exerted by the vehicle at the middle part of convex bridge is equal to the mass of the vehicle to the product of the acceleration due to gravity.

F = mg

F is the net force acting downward at the mid point of the convex bridge due to vehicle .

THANKS.

Answer 2

Explanation:

Let us consider that the vehicle is moving over the bridge with velocity "v" and radius of bridge r. Now when the vehicle reaches the midpoint, then there are two forces acting upon, that is the weight of vehicle and the centripetal force. The direction of both of these are opposite to each other.

So the weight of the truck or vehicle in the mid point would be;

W = mg = (mv²/r)
