The apparent weight of a passenger in an elevator

An elevator shaft was included in the design for Cooper Union, because Cooper was confident that a safe passenger elevator would soon be invented. The shaft was circular because Cooper felt it was the most efficient design. Later Otis designed a special elevator for the school.

From its description, this elevator appears to have been primarily for the use of passengers, but it unquestionably carried freight as well. The machine shown in figure 7 had, with the exception of a car safety, all the features of later systems driven from line shafting—counterweight, control from the car, and reversal by straight and ... An elevator accelerates upward with an acceleration of magnitude 1.5 m/s2, after which it moves with a constant velocity. As the elevator approaches its stopping point, it undergoes a downward acceleration of magnitude 0.9 m/s2. Calculate the apparent weight of a passenger with a mass of 75 kg when (a) the elevator undergoes positive acceleration If you have available several 3.0-uF capacitors, each capable of withstanding 200V without breakdown, how would you assemble a combination having an equivalent capacitance of (a) 0.50 capable of withstanding 1000 V or of (b) 1.5 uF withstanding 200 V? Elevator Calculation • The passenger is still moving in a circle, so net force is downward toward the center of the circle. Apparent Weight in Circular Motion • Newton’s second law for this motion is now: • So apparent weight is: • If v is large enough, wapp > w, just as at the bottom of the track. Apparent Weight in Circular Motion • But if the car ...

As long as the elevator moves up at a constant speed, the result stays the same because the weight . does not change. If the elevator moves up with acceleration, the critical mass is smaller because the weight of . becomes larger by an apparent weight due to the acceleration of the elevator. Still, in all cases the shorter string breaks first.
