a) A climber relies on a safety rope swing hung from a large cliff face. The diameter of the polyamide rope is 8.5 mm and the tensile strength of bulk polyamide is quoted as 138 MPa. Calculate the maximum size of person in kilograms that could utilise the rope, if a factor of safety of 6.2 is to be assumed. b) A ladder of length 5 m is resting against a smooth wall, its point of contact being just below a first floor window. The bottom of the ladder rests on the ground and the coefficient of friction between the ladder and the ground is 0.3. A person of mass 75 kg climbs the ladder, which has a mass of 4 kg. The bottom of the ladder is at the point of slipping, outward from the wallI, just as the person reaches the mid-point of the ladder's length.
