Two beams support part of a platform. • At their upper ends, the beams meet the platform at the same point. The beams are intended to rest on the ground at different points, but on the same horizontal level. The beams will both be in the same vertical plane. • The main beam is 12.5 m long and is at an angle of 38° to the horizontal. . The support beam is 7.2 m long.

a) Using a sketch, describe the problem with this design as it stands.

b) The design is revised by increasing the support bear's length to the revised design? How could it be fixed without changing either of the beam lengths again?​
