## 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

500 tonnes at the centre
200 tonnes at the left support
200 tonnes at the centre
200 tonnes at the right support

2fS = v² - u²
S = ut + ½ ft²
v = u + ft
