The upward normal force exerted by the floor on an elevator passenger is 620N. The weight of the passenger is 650N. 1. a. What are the reaction forces to these two forces? b. Find the acceleration of the passenger. A toboggan loaded with students (total weight w) slides down a snow-covered hill that slopes at constant angle α. There is virtually no friction, what is its acceleration? A highway curve with radius R is to be banked so that a...

The net force exerted on a particle acts in the +x direction. Its magnitude increases linearly from zero at x = 0, to 22.0 N at x = 3.5 m . It remains constant at 22.0 N from x = 3.5 m to x = 8.0 m , and then decreases linearly to zero at x = 13.0 m . A) Determine the work done to move the particle from x = 0 to x = 13.0 m graphically by...
The structure with a total length of 8 m is loaded by a force F= 8 kN at a distance d= 2.8 m from the support on the left. Determine the magnitude of the internal shear force (positive upward) and the bending moment (counter-clockwise positive) at a distance x= 1.4 m from the roller support on the left hand side (express your answer with the appropriate units). Vx= Mx= ---1 -Т.. B N / = positive
Figure Q1(b) shows a beam AD which is loaded with the force F. The coefficient of static friction at the top and bottom surfaces of the wedge are ???=0.25 and ???=0.35, respectively. Neglect the weight, size of the wedge and the thickness of the beam. Considering the value of F from the Table Q1(b) attached, answer the following; (i) Draw the free body diagram of the given problem with all forces and support reactions. (2 marks) (ii) Determine the horizontal...
N1 weight Work and Kinetic Energy - 4 Forces - Horizontal Motion This problem is similar to lecture example and discussion problem. As shown in the figure, a 25.5 kg block is pulled to the right by force F = 79 N. The coefficient of kinetic friction between the block and the floor is uk = 0.26. The block moves through a distance of 18.00 m. DON"T use scientific notation. Review on application of Newton's second law. Step 1: Start...
just e8.11 The company anticipated that the restorers would work a total of 12.000 hours this year. Expected parts and materials were $1.260,000 In late January, the company experienced a fire in its facilities that destroyed most of the accounting records. The accountant remembers that the hourly labor rate was $70.00 and that the material loading charge was 83.25% Instructions a. Determine the profit margin per hour on labor. b. Determine the profit margin on materials. c. Determine the total...
A spring of negligible mass stretches 3.00 cm from its relaxed length when a force of 6.80 N is applied. A 0.510-kg particle rests on a frictionless horizontal surface and is attached to the free end of the spring. The particle is displaced from the origin to x = 5.00 cm and released from rest at t = 0. (Assume that the direction of the initial displacement is positive. Use the exact values you enter to make later calculations.) (a)...
ratio. 4 A pneumatic spring consists of a piston riding on top of the air in a cylinder. The upward force of the air on the piston is given by Fair 14, where a is a constant with funny units of N m14 For simplicity, assume the air only supports the weight, Fw, of the piston itself, although in practice this device is used to support some other object. The equilibrium position, ro, is where Fw equals -Fair (Note that...
