    Ramp Statics
AI Thread Summary
The discussion focuses on solving a statics problem involving a ramp weighing 200 lb and determining the cable force and pin hinge reactions. The cable force required to ensure the reaction at point B is zero is calculated to be 195 lb, while the horizontal and vertical components of the pin hinge at point A are found to be 97.5 lb and 33.4 lb, respectively. Participants emphasize the importance of setting up equilibrium equations for all directions and considering the sum of moments to solve the problem effectively. An illustration of the setup is mentioned as potentially helpful for understanding. Overall, the key takeaway is the application of equilibrium principles in statics to find the required forces.

Given: A ramp which is sitting as illustrated below. The ramp weighs 200 lb.

Find 1: Cable force (line CD) so that the reaction at point B=0.
Find 2: Determine the Horizontal and vertical components of pin hinge at point A

Solution: I know that all the forces lie in the y-direction.
I believe I have found the usual tension in tha cable to be 173.2 lb.
I know that all the forces will be in the y-direction.

How do I set up the equation?

(Answer from textbook: F(CD) = 195 lb.)

Solution 2: done.
A(x) = 97.5 lb.
A(y) = 33.4 lb.

An illustration would be great.
 
I have one, look again

I don't see anything, unless there's something wrong with my computer. Anyway, the same old story regarding statics - set up the equations of equilibrium for every direction and see what you get. Also, the sum of all moments with respect to any point must equal zero, which may help too, perhaps.
