Question

A uniform, horizontal flagpole of length 4.90m and with a weight of 196N is hinged to a vertical wall at one end. A stuntwoman weighing 610N hangs from its other end. The flagpole is supported by a guy wire running from its outer end to a point on the wall directly above the pole.

A)If the tension in this wire is not to exceed a force of 1000N , what is the minimum height above the pole at which it may be fastened to the wall?

B)If the flagpole remains horizontal, by how many newtons would the tension be increased if the wire were fastened a distance 0.49m below this point?

Explanation / Answer

Using similar triangles, the ? distance from the pivot to the wire D = 4.9*h/?[h
