SUMMARY
The maximum mass supported by a 5.6-inch diameter suction cup mounted on a vertical wall, with a coefficient of friction of 0.65, is determined by calculating the maximum force exerted by atmospheric pressure. The calculation yields a maximum force (Fmax) of 250N, derived from the equation Fmax = pA, where p is atmospheric pressure (101.3 kPa) and A is the area of the suction cup. To find the mass, one must consider the gravitational force acting on the mass, which can be calculated using the formula m = F/g, where g is the acceleration due to gravity (9.81 m/s²).
