Question

Let us consider trolley having weight of 15 tons.Trolley has steel wheels and placed on track. Now i need to pull the trolley using winch and wheels are independent.what is force required to move trolley?i can calulate rolling friction.how to calculate the static friction required to move trolley cosider trolley weight o.5 ton and load on trolley is 14.5 ton. rolling friction is less than static friction and static friction is less than maximum possible static friction. How moment of inertia is calculated in this case considering above load and wheel load?

Answer 1

To calculate the force required to move the trolley, you need to consider both rolling friction and static friction, as well as calculate the moment of inertia. Rolling friction can be calculated, but the calculation of static friction depends on the materials involved. Moment of inertia depends on the load on the trolley and wheel loads.

Step-by-step explanation:

To calculate the force required to move the trolley, you need to consider both the rolling friction and the static friction. Rolling friction is the force that opposes the motion of the trolley and can be calculated.

However, calculating the static friction required to move the trolley depends on the maximum possible static friction, which is determined by the materials involved.

To calculate the force required to move the trolley, you need to consider both rolling friction and static friction, as well as calculate the moment of inertia.

Rolling friction can be calculated, but the calculation of static friction depends on the materials involved. Moment of inertia depends on the load on the trolley and wheel loads.

The moment of inertia in this case can be calculated by considering the load on the trolley and the wheel loads.

Moment of inertia is a measure of an object's resistance to changes in rotational motion, and it depends on the distribution of mass around the axis of rotation.
