QUESTION 4 Problem A new type of force was discovered by physicists with the following expression: a Fnew + Be* + 3x where alpha & beta are constants, and x is the position. The expression above was obtained from the interaction of a massless Higgs Boson (a type of particle) and a black hole. Quantum physicists then decides to design and build a machine that is able to move the Higgs Boson from x2 to x1. How much work should the machine do to achieve this feat? (For simplicity, consider that no energy is lost in the process) Solution To determine the work done we apply the following W = dx Evaluating the above, we get W = for the limits from xj to xe substituting x1 and x2 as the limits, the work done is expressed as W = Bi x1 ( x15

In a loop-de-loop ride at the fair a 200 Newton child experience as a 100 Newton apparent weight at the top of the loop. The diameter of the ride is 12 m. a. How fast is the child traveling at the top of the ride? b. Neglecting friction how fast is the child traveling at the bottom of the ride. c. what is the child's parent wait at the bottom of the ride d. In the reference frame of the child are they accelerating? What role does a child's inertia force play?

Lost in Space AgainContextYou are an engineer at NASA's Johnson Space Center, in charge of assisting astronauts aboard a spacecraft in orbit. You need to program a model to determine how long the ship's two secondary engines need to fire to increase its speed by a certain amount. Constraints The mass of the ship is known.The initial velocity is unknown.The desired speed increase delta V is known.Both motors are similar and exert a known force. They are located on either side of the ship and each generates a force matched to a (known) angle theta to the direction of the ship. Modelization Models the ignition time required for the ship to increase its speed by delta V given the known parameters. Then test your model with the following parameters: Shuttle mass: 1912500 kg; Strength of each motor: 4800000 N; The orientation angle of the motors: 15 degrees; Desired speed increase: 530 km/h.

F1 RDY RAY The figure above is a pin-joint frame with horizontal member length l = 3m and vertical member length h = 5m. (Note that the diagram is not to scale.) You are given that F = 48KN, RAY = 16KN and Rpy = 32kN. Use the method of sections to calculate the forces in members BC, FC and FE.

Example A man having the mass of 175kg sits in the chair which is pin- connected to the frame BC. If the man's always seated in an upright position, determine the horizontal and vertical reactions of the chair on the man at the instant 0 = 45° at this instant he has a speed of 6 m/s, which is increasing at 0.5m/s^2 A Tom B
