6. 1) The uniform slender 15-kg bar of length / = 2.6 m rests on smooth surfaces but starts to slide in a way that the contact point at A moves to the left while the contact point at B moves downwards. If at this instant the angle = 70°, and the normal force at point Bis 2.0 N, determine the angular acceleration (in rad/m2) of the bar at this instant. Negative sign must be included if the angular acceleration is clockwise. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point. Take g = 9.81 m/s2. B 1 Ө
6. 2) The uniform slender 11-kg bar of length /= 2.9 m rests on smooth surfaces but starts to slide in a way that the contact point at A moves to the left while the contact point at B moves downwards. If at this instant the angle 0 = 52°, and the normal force at point Bis 3.3 N, determine the normal force at point A at this instant. Please pay attention: the numbers may change since they are randomized. Your answer must include 2 places after the decimal point, and proper Sl unit. Take g = 9.81 m/s2. B 1
