Tension at an angle from hanging mass

In summary, the conversation discusses a problem related to a bar and cable and the use of pulleys. The person is experiencing pre-exam stress and asks for clarification on the problem, specifically the direction of the bar's force and how to solve for tension. The solution involves drawing a free body diagram and splitting the tension into horizontal and vertical components, with the understanding that the forces must be equal for the mass to be in equilibrium. The person also apologizes for their multiple posts and thanks for the late reply.

I apologize for my multiple recent posts, but I'm having pre-exam stress, so even the simplest things seem nearly impossible. Haha..

Homework Statement

Note that connection point between the bar and the cable is not a pulley.


Homework Equations


F=ma


The Attempt at a Solution


The problem seems to be pretty straightforward, but would T=800N? (We use 10 m/s2 for acceleration due to gravity.) And also, what would clue me into whether the bar pushes or pulls on the ropes?

Thanks!

Draw a free body diagram of the hanging mass. You should have the tension, weight, and force the bar exerts. Split the tension into horizontal and vertical components.

The mass is in equilibrium so the left/right and up/down forces must be equal that should clue you in as to what direction the bar force is exerting.

It should be pretty straight forward to solve for tension now also.

Sorry for the late reply, but would this be the correct way to approach this?

1. What is meant by "tension at an angle" when discussing a hanging mass?

When discussing a hanging mass, "tension at an angle" refers to the force acting on the mass in a direction that is not purely vertical. This means that the force of tension is not only pulling the mass straight up, but also at an angle. This is commonly seen in situations where the hanging mass is attached to a string or rope that is not perfectly vertical.

2. How is the tension at an angle calculated?

The tension at an angle can be calculated using trigonometric functions such as sine, cosine, and tangent. These functions take into account the angle at which the string or rope is attached to the mass, as well as the weight of the mass itself. The specific equation used will depend on the given variables and the situation being analyzed.

3. What factors influence the tension at an angle in a hanging mass?

The tension at an angle in a hanging mass is influenced by several factors, including the weight of the mass, the angle at which it is hanging, and the properties of the string or rope used. Additionally, external forces such as wind or other objects can also affect the tension at an angle.

4. How does tension at an angle affect the stability of a hanging mass?

The tension at an angle can greatly affect the stability of a hanging mass. If the angle of the string or rope is too steep, the tension on the mass may become too great and cause it to fall. On the other hand, if the angle is too shallow, the tension may not be strong enough to hold the mass in place. It is important to consider the tension at an angle when hanging objects to ensure stability.

5. Can tension at an angle from a hanging mass be negative?

Technically, tension at an angle from a hanging mass can be negative if the force is acting in the opposite direction of the weight of the mass. However, this is not a common occurrence in typical hanging mass situations. In most cases, the tension at an angle will be positive, meaning it is pulling in the same direction as the weight of the mass.
