Solving Wheel and Forces Homework: Show Weight of Wheel is 180N

In summary, the question asks about the weight of a wheel resting on a kerb and the force needed to move it over the kerb. Using the equation Moment = Perpendicular force x distance, the weight of the wheel is found to be 180N. The poster also mentions seeking help on a forum.

Homework Statement


Hi
I am not sure about this question. Can anyone help?

It states this way:
A wheel of radius 0.5m rests on a level at a point C and makes contact with the edge E of a kerb of height 0.2m. A horizontal force of 240N, applied through the axle of the wheel at X, is required just to move the wheel over the kerb. Show that the weight of the wheel is 180N.





Homework Equations


Moment = Perpendicular force x distance



The Attempt at a Solution


I was thinking of taking moments but not even sure how to begin.

Related to Solving Wheel and Forces Homework: Show Weight of Wheel is 180N

1. How do you calculate the weight of a wheel?

The weight of a wheel can be calculated by using the formula W = m x g, where W is the weight, m is the mass of the wheel, and g is the acceleration due to gravity (9.8 m/s² on Earth).

2. What is the unit of measurement for weight?

The unit of measurement for weight is newtons (N). One newton is equal to the force required to accelerate a mass of one kilogram by one meter per second squared.

3. How does the weight of a wheel affect its performance?

The weight of a wheel can significantly impact its performance. A heavier wheel will require more force to rotate, leading to slower acceleration and more energy consumption. On the other hand, a lighter wheel can result in better handling and quicker acceleration.

4. Can the weight of a wheel be reduced?

Yes, the weight of a wheel can be reduced by using lighter materials such as carbon fiber or aluminum, or by changing the design to reduce the amount of material needed. However, this may also affect the strength and durability of the wheel.

5. How can the weight of a wheel be measured?

The weight of a wheel can be measured using a scale or by using a force meter to measure the force required to support the wheel. This force can then be converted to weight using the formula W = F x d, where W is the weight, F is the force, and d is the distance from the center of the wheel to the point of support.
