Taking a slice (section cut) between points A and B, the left side of the cut is drawn below. Draw a free body diagram (FBD) of the /eft side of the cut. Be sure to establish a local coordinate system (LCS). Include all internal forces and moments at the cut as well as all external loads. Ry aoa me q Ry Ya 2 Y wes x 4.

In the structure below, the U-shaped structure ABECD is clamped at point D and has a load P=100 Ibs to the left at point A. Member BEC has a rectangular cross section with height 0.4” and width 0.1”. Members AB and CD have identical dimensions. For the loading shown, determine the internal loads (forces and moments) at section E, which is midway between points B and C. si < P=100 Ibs A 6” k 0.4” 24  aaa lov Ibs a SINCE CANTILE VERED, CAN Find (INTER WAL LOAD!
