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

Click For Summary
SUMMARY

The discussion centers on a statics problem involving a beam structure fixed at point C and supported by a cable BD. The problem specifies two concentrated forces, F1 at 700 N and F2 at 400 N, with a cable tension of 1250 N. The manual incorrectly states the reaction force at C as 80.77 N, suggesting a subtraction of 50 N from F2 to align with the user's calculations. The user acknowledges a transcription error in their solution, confirming the need for careful review of calculations in statics problems.

PREREQUISITES

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
