How can I solve the problem below.
The mechanism shown is acted upon by the force P of magnitude P=20 lb. Knowing that teta=25 degree and that the coefficient of static friction between collar C and the horizontal rod is 0.30, determine the range of values of Q for which equilibrium is maintained.
I included the mechanism drawing with this question attached.© BrainMass Inc. brainmass.com October 9, 2019, 3:35 pm ad1c9bdddf
Please see the attached file.
Take point of B as the reference point :
Let pressure on C be K and F can be in both directions -0.3K<=F<=0.3K
So to keep BCD not ...
This solution is 109 words and included as an attached .doc file. It explains through step-by-step calculations how to calculate Q while maintaining equilibrium.
