An 80-cm uniform 10-kg bar is resting on two scales, one at either end. a smaller 4-kg mass (m) is placed at a distance of d = 20 cm from the left end. because the mass is closer to the left scale, it reads a higher weight than the right scale. what is the difference between the weights read by the two scales (left scale minus right scale)?

Answer

given,

length of bar = 80 cm

mass of the bar = 10 kg

smaller mass = 4 kg

distance = 20 cm

taking moment about B

difference between two scale = 8 - 6

dec 23, 2016 - a load of bricks weighing 680 n a distance of 10 m across a parking lot. if if the worker pushes the cart with a constant force of 209 n, what work= force x distance = 220 n x 10 m = 2200 n.m = 2200 j i don't know where the person got it from, but the initial part, work= force x distance me.
