Asimply-supported beam is loaded in 3-point bending with a vertical force of 1000 lb. the beam has a span of 22 in., and the load is applied at the center of the span. strain gages are mounted on the top and bottom beam surfaces, midway between the load point and the end support (i. e. 5.5 in. from the support). details for three different beam cross sections are given below. assume es = 30 × 106 psi for steel and ep = 0.38 × 106 psi for abs plastic. for each beam cross section: configuration #1: abs plasticconfiguration #3: abs plastic + 2 steel platesconfiguration #2: abs plastic + steel plate2"2"0.125"2"2"0.125"0.125"2"2" (a)calculate the normal strains εacting at the top and bottom strain gage locations. report your answers in "microstrain" (με). (b)compare the values from (a) to the measured strains, and report the errors (in με). recall: [με] = [ε] × 106
