A chimney of height 20 m is supported by a set of three ropes. The ropes are attached to the chimney at 2 m from the top and are anchored 3m above the ground at a distance 10 m from the axis of the chimney. Draw the projections of the ropes if the anchor points are due north, south-east and south west of the chimney. Find the true length and slope in relation to the ground of one of the ropes. (The chimney and ropes may be considered as lines for the projections). A suitable scale may be used. (sir please give solution of this Question )
