- The tension in the cable, T, upward. - The weight of the elevator+passenger, downward, which is given by. W = mg. where m=1700 kg is the mass and g=9.81 m/s^2 is the acceleration In this second part of the trip, the elevator continues at constant velocity. This means that the acceleration is zero

in an elevator accelerating upward with acceleration a . What is the fraction immersed? SA 10.16 The sap in trees, which consists mainly of water in summer, rises in a system of capillaries of radius r = 2.5×10–5 m. The surface tension of sap is T = 7.28×10–2 Nm–1 and the angle of contact is 0°.

Physics. If the 480 kg elevator carries a load limit of 24 passengers (ave mass is 70kg per person) what is the max possible upward acceleration of the elevator without breaking cable? #"Tension - weight= ma"#. In this case, total mass is. #480+24*70=2160kg# So #weight =mg=2160*.9.81=21,190N.

ELEVATOR WORKSHEET. The "Elevator Problem" is a classic problem in physics. The situation is this: "You are standing on a bathroom scale in an elevator. You are holding an apple. (Yes, people are staring at you...) You weigh 500 Newtons, so your mass is about 50 kg." This assignment is a step-by-step analysis of the elevator problem.

Aug 17, 2011 · Physics tension problem? a 44-kg chandelier is suspended 1.5m below a ceiling by three wires, each of which has the same tension and the same length of2.0m find the tension in each wire. Posted by Elinore Freggiaro at 2:12 PM

Apr 15, 2016 · A 60.0 kg student is riding the elevator at the CN Tower in Toronto. Calculate her apparent weight if she is accelerating upwards at a rate of 5.20 m/s 2. Calculate her apparent weight if she is riding down the elevator. Include a solution with the derived equation for each. Homework Equations F=ma The Attempt at a Solution

This is a classic introductory physics problem. Basically, you have a cart on a frictionless track (call this m 1) with a string that runs over a pulley to another mass hanging below (call this m ... Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. Determine tension $T$ in the string when elevator moves in $x$ direction. Since at this point, the bob is in equilibrium, the tension in the string must be equal to the magnitude of the...

Elevator Physics. Imagine that you're in an elevator. Sketch separate free-body diagrams for you, the elevator by The elevator's free-body diagram has three forces, the force of gravity, a downward normal force from you, and an upward force from the tension in the cable holding the elevator.Sep 27, 2011 · Find the tension in each of the two ropes supporting a hammock if one is at an angle of theta 1= 16 degrees above the horizontal and the other is at an angle of theta 2 = 35 degrees above the horizontal. The person sleeping in the hammock (unconcerned about tensions and ropes) has a mass of 65 kg . What is the tension in each of the 2 ropes? (find T1 and T2) This Physics Girl video highlights seven different surface tension experiments that you can easily try at home or in the classroom. Have any of these around? A plate, a glass, a penny, an index card, a paperclip, an eye dropper, a cup of coffee, dish soap, or some food coloring… and if you’re teaming up with an adult, get a pan and stove, too.

This tension calculator will help you determine the tension forces acting in a rope, string, or any tension members that undergo pulling or stretching forces. You can calculate for tension forces in ropes pulling objects on a frictionless surface as well as tension forces in ropes that are suspending an object.

What is the tension in the top rope? What is the tension in the rope connecting the two boxes? Consider an alternative situation in which the system has the same acceleration but the rope between the boxes is not lightweight. It is a steel cable with a total mass of 1.0 kg. What would be the force of the steel cable on the top box?

A. The two forces acting on the box are Fspring and Weight. As the elevator accelerates upward, the spring will be compressed. Hence, L would be smaller than 1 meter. C. Since the force of gravity is pulling down and the force of the elevator is pulling up, the tension on the spring is the sum of those tow forces and hence

The elevator is supported by a cable. The diagram below is a free-body force diagram for when the elevator is moving upwards during the first 0.50 s. tension weight (d) In the space below, draw free-body force diagrams for the elevator during the following time intervals. (i) 0.5 to 11.50 s (ii) 11.50 to 12.00 s (3)

Oct 01, 2009 · Homework Statement An elevator cable can stand a maximum tension of 19000N before breaking. The elevator has a mass of 520 kg, and a maximum acceleration of 2.16 m/s^2. Engineering safety standards require that the cable tension never exceed two-thirds of the breaking tension.
