So for a general frame displacement, if I look at the pure rotational deformations, these would be due to the differences in the shear forces (Y2 - Y1) and (X2 - X1). These deformations would be 'constrained' by the given geometry of the frame, as shown in the attached photo. (Again assuming...
Three degrees of freedom: x and y translations and rotation about z-axis. In the case of translations, the two different x deformations must be identical and the two different y deformations also must be identical. In the case of rotation about z-axis, the two different x deformations must be...
Umm, can I say that the x-direction deformation of pad #1 and that of pad #2 have to be the same given that the steel frame is rigid? Also for pads #3 and 4. As for the y-direction deformations would be equal for pads 1 and 4 (and for pads 2 and 3). Are these correct assumptions to make?
Homework Statement
Solve for support reactions of a rigid, rectangular steel frame sitting on rubber pads at the four corners (See attached), when a shear force and a moment is applied at some point on the frame. All the known variables are shown in black while the unknown are in red. It is a...
