You are working for a high power insurance company in Hollywood and have been asked to consult with the film crew to decide whether or not this is possible using the flagpole on a nearby building. You are all too aware that no one could survive the 100m fall from the flagpole to the ground. The flagpole is a 60kg steel I-beam which is very strong and rigid. One side of the flagpole is attached to the wall of the building by a hinge so that it can rotate vertically. 3m away, the other end of the flagpole is attached to a strong, lightweight cable. The cable goes up from the flagpole at an angle of 30 to the horizontal until it reaches the building where it is bolted to the wall. Harold weighs 75kg. From the specifications of the building construction, both the bolt attaching the cable to the building and the hinge have been tested to hold a vertical force of 1020N. The director decides that the most dangerous moment will be when Harold reaches the far end of the flagpole, three meters from the building, is this correct, is Harold safe provided he doesn't reach the end?
