Restriction of motion

  1. Oct 24, 2015 #1
    1. The problem statement, all variables and given/known data
    the whole structure wouldnt turn about x , y, and z direction , am i right ? why there are no moment restriction in this case(bottom) just in the above case , namely M_AZ and M_AX

    2. Relevant equations

    3. The attempt at a solution

    The placement of the hinge at C and the bearing at A pretty much eliminate the possibility of any rotational motion. All that's left is to balance the applied load and the reaction forces.

    ya , why no sign of restriction of moment are indicated on the diagram ?
