Calculate the normal reaction forces at A and B.Answers:NA =! IbNg =i! Ib The 153-lb exerciser is beginning to execute a bicep curl. When in the position shown with his right elbow fixed, he causes the 17-lbcylinder to accelerate upward at the rate 0.25g. Neglect the effects of the mass of his lower arm and estimate the normal reactionforces at A and B. Friction is sufficient to prevent slipping.20°63"17 lbB-11"13"

Given- W = 153 lb. Wc = 17 lb ac = .25g

For the beam shown, the magnitude of the distributed load is wo = 10.6 kN/m and the beam lengths are a = 6.3 m and b = 18.9 m. (a) derive equations for the shear force V and the bending moment M for any location in the beam. Place the origin at point A. (b) use the derived functions to plot the shear-force and bending-moment diagrams for the beam. Use your diagrams to determine the maximum shear force and the maximum bending moment. Note that answers may be positive or negative. Here, "maximum" refers to the largest magnitude value, but you should enter your shear force and bending moment with the correct sign, using the sign convention presented in Section 7.2 of the textbook. If the magnitudes of the largest positive and largest negative values are the same, enter a positive number. Wo В a
