Question

A workman is required to machine a casting of 210 kg mass on a lathe. He fixes it in such a way that the centre of gravity of the casting is 180 mm from the lathe axis and 320 mm from the face plate. He balances it statically by bolting two weights to the face plate, one of them has 60 kg mass and is fixed as shown in fig (2). The radial distance of the weight is 270 mm and the c.G. Is at a distance of 160 mm from face plate. The other is 50 kg and its cg is 100 mm from the face plate. Determine:- (i) the radial and angular position of 50kg weight and (ii) the rocking couple at 50 rpm
