Solved: The masses mA and mB slide on the smooth
Chapter , Problem 69(choose chapter or problem)
The masses mA and mB slide on the smooth (frictionless)inclines fixed as shown in Fig. 4-55. (a) Determine a formulafor the acceleration of the system in terms of raA, raB ,dA ,dB,and g. (b) If 0A = 32, 0B = 23, and raA = 5.0 kg, whatvalue of raB would keep the system at rest? What would be thetension in the cord (negligible mass) in this case? (c) Whatratio, mA/mB, would allow the masses to move at constantspeed along their ramps in either direction?
