The 162-lb exerciser is beginning to execute a bicep curl. When in the position shown with his right elbow fixed, he causes the 19-lb cylinder to accelerate upward at the rate 0.20g. 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. 21° 61" 19 lb -10" 10" 13"
