# Force in two dimennsional frames

• tariqb
In summary, the problem involves a pin-jointed frame with a 60/30 degrees triangle shape, supported by a vertical wall 0.45m apart and with a horizontal lower frame member. The hanging load is 6kg, and the task is to calculate the forces in the two frame members and the reactions at the wall supports. To solve this problem, a free-body diagram can be drawn and equations can be used. It is also important to consider a possible vertical reaction at the lower wall support.

Hi tariqb ! Welcome to PF!

Show us what you've tried, and where you're stuck, and then we'll know how to help.

tariqb: Did you draw a free-body diagram showing the reactions at the two wall supports yet? Do you know any equations you could use to solve this problem? Do you think there is a vertical reaction at the lower wall support?

## 1. What is force in two dimensional frames?

Force in two dimensional frames refers to the application of a push or pull in a specific direction in a two dimensional space. It is a vector quantity, meaning it has both magnitude and direction.

## 2. How is force represented in two dimensional frames?

In two dimensional frames, force is typically represented by a vector arrow. The length of the arrow represents the magnitude of the force, while the direction of the arrow represents the direction in which the force is acting.

## 3. What is the difference between a force and a force vector?

A force is a physical quantity that can cause an object to accelerate or change its motion. A force vector, on the other hand, is a graphical representation of force that includes both magnitude and direction.

## 4. How do forces interact with each other in two dimensional frames?

In two dimensional frames, forces can interact with each other in two ways: they can either act in the same direction and add together, or they can act in opposite directions and cancel each other out.

## 5. What are some common examples of forces in two dimensional frames?

Some common examples of forces in two dimensional frames include tension, friction, normal force, and gravitational force. These forces are often present in everyday situations, such as pulling on a rope or sliding an object across a surface.
