    Torques
In summary, torque is a measure of the force that causes an object to rotate around a fixed point or axis. To calculate torque, you need to know the magnitude of the force applied and the distance between the point of rotation and the point where the force is applied. Finding the load on piers supporting a 700N girder is important for determining the stability and safety of the structure. Factors such as the weight of the girder, additional objects or people, distance between piers, and angle of force can affect the torque on a girder. If the torque exceeds the maximum load capacity of the piers, it can cause the structure to become unstable or collapse.

A uniform girder weighing 700N is 3.0m long. It is placed horizontally on top of two narrow piers which is support it at points 30cm and 60cm respectively from its ends. Find the load carried by each pier.

Nice description.
So how are you attempting this problem?
 

What is a torque?

A torque is a measure of the force that causes an object to rotate around a fixed point or axis. It is usually represented by the symbol "τ" (tau).

How do you calculate torque?

To calculate torque, you need to know the magnitude of the force applied and the distance between the point of rotation and the point where the force is applied. The formula for torque is τ = r x F, where r is the lever arm or distance, and F is the force applied.

What is the significance of finding the load on piers supporting a 700N girder?

Finding the load on piers supporting a 700N girder is important because it allows us to determine the amount of weight or force that each pier is bearing. This information is crucial for ensuring the stability and safety of the structure.

What factors can affect the torque on a girder?

The torque on a girder can be affected by several factors, including the weight of the girder, the weight of any objects or people on the girder, the distance between the piers, and the angle at which the force is applied.

Can the torque on a girder be too high?

Yes, the torque on a girder can be too high. If the torque exceeds the maximum load capacity of the piers supporting the girder, it can cause the structure to collapse or become unstable. It is important to carefully calculate and monitor the torque on a girder to ensure the safety of the structure.
