Applied Mechanics and Graphic Statics A cable loaded with 0.5 tonne per horizontal metre span is stretched between supports in the same horizontal line 400 m apart. If central dip is 20 m, the minimum tension in the cable, will be 200 tonnes at the left support 200 tonnes at the centre 200 tonnes at the right support 500 tonnes at the centre 200 tonnes at the left support 200 tonnes at the centre 200 tonnes at the right support 500 tonnes at the centre ANSWER DOWNLOAD EXAMIANS APP
