Calculating Forces on a Cantilever: Physics Homework Problem

In summary, a 3 m long cantilever with a mass of 250 kg is attached to a wall and held in place by a steel cable at a 30° angle. A 5 kg mass hangs from the far end of the cantilever. The problem involves solving for the horizontal and vertical components of the force acting on the cantilever using the equations for moment of inertia and torque. A figure is needed to better understand the problem.

Homework Statement


A 3 m long cantilever with a mass of 250 kg is
attached to a wall and also held in place by a steel cable
that is attached to the far end of the cantilever at an angle
of 30° with respect to the cantilever as shown in the figure
at right. A 5 kg mass also hangs from the far end of the
cantilever. Solve for the horizontal and vertical components of this force and use them to determine the magnitude of the force acting on the cantilever.



Homework Equations


I= (1/12)M(L^2)
t=r X F


I just have no idea where to even begin.

FAQ: Calculating Forces on a Cantilever: Physics Homework Problem

What is a cantilever?

A cantilever is a type of structure that is supported at one end and free to move at the other end. It is commonly used in bridges, buildings, and other engineering applications.

What is a cantilever physics problem?

A cantilever physics problem is a question or scenario that involves analyzing the forces and stresses acting on a cantilever structure. It may involve calculating deflection, stress, or other factors to determine the stability and safety of the structure.

What are the key factors that affect a cantilever's stability?

The key factors that affect a cantilever's stability include the length of the cantilever, the material it is made of, the load applied to it, and the support at the fixed end.

How do engineers use cantilever physics in real-world applications?

Engineers use cantilever physics to design and analyze various structures such as bridges, buildings, and cranes. They use mathematical equations and principles to ensure that the cantilever can withstand the expected loads and remain stable.

What are some common solutions to cantilever physics problems?

Some common solutions to cantilever physics problems include adjusting the length or material of the cantilever, adding additional supports, and redistributing the load. In some cases, engineers may also use reinforcement techniques such as adding braces or trusses to improve the structure's stability.
