The 198-lb exerciser is beginning to execute a bicep curl. When in the position shown with his right elbow fixed, he causes the 23-lb cylinder to accelerate upward at the rate 0.30g. Neglect the effects of the mass of his lower arm and estimate the normal reaction forces at A and B. Friction is sufficient to prevent slipping.
