Im new to physics and I am trying to do some problems here, I hope someone can help me, here it goes : If a passenger with a mass of 72.2kg stands on a weight scale in a elevator. What is the reading on the scale if the elevator goes down with a constant acceleration of 3.20 m/s^2. Dumbwaiter Installation Labor Cost. The average cost to install an electric two-stop dumbwaiter is $10,000. Out of this cost, $6,000 is the cost of the dumbwaiter unit, while around $4,000 is the cost of installing a dumbwaiter. Installing a dumbwaiter in an existing shaft takes about four to six hours and averages $750 to $2,500 while The major advantage of a shaft-less elevator is the option to have it installed in a completely open floor plan. The ASME A17.1 and A17.7 2010 elevator code permit a home elevator to travel between one floor without an enclosure. If the elevator is not enclosed the code requires several other safety devices and provisions. The nominal handling capacity of a 1000mm wide escalator running at 0.75 m/s is quoted in EN 115: 1995 as 13,500 passengers/hour. This is based on a factor of two passengers per step. Although it Philip - The maximum speed of ascent and descent is set by how much the pain the passengers can reasonably bear. Lift manufacturers can get round the problem a bit by pressurising the lift but, even so, the new and fancy 40 miles per hour lifts can only go up the building at that speed, they come down at a much more sedate 22 miles per hour. Weight limit of elevator = 630 kg. Weight of heaviest person in the lift = 57 kg . Weight of lightest person in the lift = 53 kg . To get the maximum number of people in the lift, we will take the people who have the minimum weight. Now , let us suppose there are ' n ' people of 53 kg weight. So, The total number of people in the lift XyGbQeP.
