UESTION 3
A cable 54m long is attached between supports at A and B as shown in below figure. The tension
at support B is cqual to the weight of 23m of cable. The angle of inclination of the cable
at B is 31°.
.I.I Determine the height of point A above that of point B.
.1.2 If the cable at A passes over a frictionless pulley to form a backstay at 45° to the horizontai,
calculate the reaction at the support. (assume a mass of 22kg/m for the cable)
y.
ground level
3.2 A cable is suspended between two points P and Q which are 200m horizontally apart. P and Q
are on the same level and 8m higher than the lowest point in the cable.
3.2.1 Find the maximum tension in the cable and the slope at the support if the cable carries 10kN
per horizontal metre.
3.2.2 What is the tension 25m from P.
