Hello guyz,i'm facing this problem in my statics class...and thought posting it here so i can get some help :)

here it goes

Ok this is what i did and I'm kinda stuck...

just bare with me

I'm not able to find The angle between The reaction at point A and the X-axis so i can project... any suggestions?

and plus how shall i decompose the weight ?

Hi JosephR!

Since the only given force, the weight, is vertical, it would be simpler to make the x and y directions horizontal and vertical, and to split the normal and pulling forces into N_x N_y B_x and B_y.

Then take moments about B and A.

Hello,

I understand that you are facing a problem in your statics class and are seeking help. I am a scientist and would be happy to provide some advice on how you can approach this problem.

Firstly, it is important to understand the concept of statics and the principles involved. Statics deals with the study of forces and their effects on stationary objects. In this problem, you are dealing with a rigid body that is in equilibrium, meaning that the forces acting on it are balanced and there is no net force or acceleration.

Now, looking at the problem, it seems like you have correctly identified the forces acting on the body - the weight and the reaction forces at points A and B. To find the angle between the reaction at point A and the X-axis, you can use trigonometry. Since you have already found the magnitude of the reaction force at point A, you can use this value along with the known value of the weight to find the angle. You can also use the Pythagorean theorem to find the third side of the triangle and then use trigonometric ratios to find the angle.

As for decomposing the weight, you can break it down into its components along the X and Y axes. Since the weight is acting vertically downwards, its component along the X-axis will be zero and its component along the Y-axis will be equal to its magnitude. This will help you in balancing the forces along the X and Y axes separately.

I hope this helps you in solving the problem. Remember to always approach statics problems by first understanding the principles involved and then using appropriate mathematical techniques to solve them. If you still have any doubts, don't hesitate to seek further clarification from your professor or classmates. Good luck!
