Statics - I think I found a mistake in the solution manual - need confirmation

AI Thread Summary
The discussion revolves around a statics problem involving a beam structure with concentrated forces and a cable tension. The original poster identifies a potential mistake in the solution manual regarding the reaction force at point C and the fixation moment Mc. They suggest that the manual's answer for Cx could be adjusted by subtracting 50 N from F2. The conversation includes light-hearted banter about the miscopying of the problem and its implications on the solution. Overall, the participants confirm the need for careful verification of calculations in statics problems.

Homework Statement



http://img860.imageshack.us/img860/6320/tthing.jpg

In the drawing is described a beam structure fixed at point C, and held by a cable BD to the floor. The beam is loaded by two concentrated forces, F1 and F2, as described in the drawing.

Given

F1 = 700 [N]
F2 = 400 [N]

If it's known that the cable tension equals 1250 [N], calculate:

A) The reaction force at C
B) The fixation moment Mc at point C.

Ignore weight of cable and structure. Measurements are in mm.

Manual says

Cx = 80.77

I think your answer would fit if you subtract 50 N from F2.

Would that work for you too? :wink:
 
*slaps forehead* I mis-copied the print to my solution, then!

Thanks for catching it up! :smile:

How is your forehead nowawadays?

Any bruises? Noticeable brain damage? :-p

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
