NAME: Exam 4 Engr225 Problem 1 (S0 pts) Explain your work y The figure shows the cross-section of a beam. The beam is subjected to various forces and moments that cause internal loadings at the cross-section shown. Soo E Omm FEeo The figure shows the cross-section of interest and three differential elements D, E, and F. D is at the bottom and centered on the y-axis. E and F are on the side, F is on the z- axis, E's location is indicated in the figure. Z x 4 oo 40mmy The internal loadings are given with respect to the coordinate axes shown: A10.u00 NA N,=+600N M 0 C. +500N M,+20Nm V -200N M,-50Nm Your task will be to find the stresses produced by each of the loadings at a small stress element at E, and to then find the total state of stress at point E. Note that the black face in the stress element at E in the figure is represented as the shaded area in the little cube below. The front face in the cube below is in the actual cross-section. For each loading: Give a brief explanation, this could be the applicable equation plus values For normal stresses, explicitly state whether they are tensile or compressive. For each loading, indicate the resultant stress in the stress element on the side, by drawing arrows and giving the numerical value. a. At point E, finds the stress produced by the axial force, N.
