Answer to Question #67615 in Mechanics | Relativity for ciara
The long arm of a crane tower is 19 m long, while its short arm is 8 m. The weight of former is 100 kg while the latter is 40 kg. Its designed maximum hanging load is 50 kg. The fixed counterweight (G3) at the end of the short arm is of 100 kg. What should the weight be for the movable counterweight (G2), which can move from the supporting column to the end of the short arm? Assume that G2 is very short, and the masses of long and short arms are uniform, respectively.
m = (50 kg * 9.8 m/s2 * 19 m - 100 kg * 9.8 m/s2 * 8 m + 140 kg * 9.8 m/s2 * 5.5 m)/(9.8 m/s2 * 27 m) = 34 kg
I have no more assignments.
Thank you for all the help! With 19 credit hours, their is always one class that hits the back burner, with your help i was able to get a B in this class and am going to Walk on graduation.
