Answer 1

The support reactions at points A, F, and E can be determined by applying the principles of static equilibrium and solving the equations of equilibrium.

Step-by-step explanation:

To determine the support reactions at points A, F, and E, we can start by analyzing the forces acting on the structure. We have a force of 250 N at point B, which is directed downwards. We also have the weight of the structure acting downwards at point D.

Let's consider the vertical equilibrium first. The sum of all vertical forces must be zero for the structure to be in equilibrium. We have the force at B and the weight of the structure acting downwards, so the sum of these forces must be equal to zero.

Next, let's consider the horizontal equilibrium. The sum of all horizontal forces must be zero for the structure to be in equilibrium. We have the horizontal component of the force at B and the horizontal component of the weight of the structure acting towards the left. The sum of these forces must be equal to zero.

By solving these equations of equilibrium, we can determine the support reactions at points A, F, and E.
