How do I determine the support reactions at A & E in this example?
Help is much appreciated.

This indicates that the direction in which you assumed the reactions are acting is opposite of the direction in which they act.smr101 said:Right I've worked it out.
I've got E vertical as 50kN.
A horizontal as -30kN, vertical as -50kN.
Only problem is the answers have them listed as these values but I have all of the signs wrong.

∑M = (10 x 3) + (20 x 6) - (E x 3)
The purpose of determining support reactions at A&E is to analyze and understand the forces acting on a structure, such as a building or bridge, in order to ensure its stability and safety.
Factors involved in determining support reactions at A&E include the weight and distribution of the structure, external forces such as wind or earthquakes, and the material properties of the structure itself.
The process of determining support reactions at A&E involves using mathematical equations and principles of statics to calculate the forces acting on the structure and determine the reactions at its support points.
It is important to accurately determine support reactions at A&E in order to ensure the safety and stability of the structure. Incorrect calculations or assumptions about the support reactions could lead to structural failure and potential harm to people and property.
Determining support reactions at A&E can be done manually using equations and calculations, but computer software can also be used to assist with more complex structures or to save time and increase accuracy.
