It is given that the maximum weight limit is 630. The lightest person's weight is 53 Kg and the heaviest person's weight is 57 Kg. In order to have maximum people in the lift, all the remaining people should be of the lightest weight possible, which is 53 Kg. Let there be n people. 53 + n(53) + 57 = 630. n is approximately equal to 9.8.
O= 6.75 (c) What mean weights (in pounds) for a sample of 16 people will result in the total weight exceeding the weight limit of 2,500 pounds? The mean weight of 16 persons needs to be greater than 156.25 lbs to exceed the weight limit of the elevator. (d) What is the probability that a random sample of 16 people will exceed the weight limit?
The population of weights for men attending a local health club is normally distributed with a mean of 173− Ibs and a standard deviation of 25-lbs. An elevator in the health club is limited to 33 occupants, but it will be overloaded if the total weight is in excess of 6039-lbs. a. Assume that there are 33 men in the elevator.
The average cost of this elevator type is $5,000 to $20,000. Outdoor Elevator. In some cases, a house just may not be able to retrofit an elevator, or it needs to be added on a tight budget
If the median weight of the eight people is less than or equal to 1,500 pounds, then the group can safely use the elevator. On the other hand, if the median weight is greater than 1,500 pounds, then the group may exceed the maximum capacity of the elevator and it would not be safe for them to use it.

The HydroFit elevator is a self-contained system that uses Otis’ proven holeless hydraulic design. Key components were redesigned to be more compact and able to fit in a standard hydraulic hoistway, eliminating the need for a machine room. Remains the same as a conventional system: • Hoistway depth • Hoistway width • Pit depth

An elevator in a building can carry a maximum of 10 persons, with the average mass of each person being 68 kg. The mass of the elevator itself is 920 kg and it moves with a constant speed 3 m/s. The frictional force opposing the motion is 6000 N. If the elevator is moving up with its full capacity, the power delivered by the motor to the elevator g=10 m/s2 must be at least
