Q1) Pulley systems containing one, two, and three pulleys are shown. Neglecting the weights of the pulleys, determine the force T required to support the weight W in each case. W (a) One pulley W (b) Two pulleys W (c) Three pulleys

A lever has the following dimensions: Resistive force distance: 15 cmEffort force distance: 85 cm If you can exert a maximum effort force of 800 N, what is the maximum resistive force you can lift with the lever?

a) For each of the weightless and frictionless pulley systems (a) to (e) in Figure Q5a: Determine the tension (T) required to lift and hold a 1450 N crate in static equilibrium for each of the pulley systems (a) to (e). Use g = 9.81 m/s2 and give your answers in newtons (N) to two decimal places. (i) Determine the ideal mechanical advantage (IMAPulley) for each of the pulley systems (a) to (e). (ii) (iii) Determine the reaction force where the pulley wheel is connected to the ceiling for each of the pulley systems (a) to (e). Use g = 9.81 m/s² and give your answers in newtons (N) to two decimal places. (a) (b) T (c) T (d) T (e) T

Work You are moving, which requires that you push a box up hill (as shown below). The box has a mass 27.0 kg and the hill has an angle of 31.0 There is friction between the box and the hill. You push with a constant force parallel to the hill of Push = 225.0 N and the box moves with a constant velocity = 4.00 m/s up the hill. The time it takes you to push the box up the hill is 8.50 s. What is the work you do pushing the box up the hill? * You can find the distance you pushed with the information given. Motion Воx Your answer should include the following: 1 Decimal Place Correct SI Units Appropriate sign (only needed for negative answers) Answers must be in the following format: Written out and NOT in scientific notation Acceptable: 278.40 Not Acceptable: 2.784 x 102 Your Answer: Answer units

All of the following are TRUE regarding levers EXCEPT O a lever can increase the effect of force application to a body O a lever can increase the speed with which a body can be moved O a lever can increase the distance through which a body can be moved in a given time O the effect a lever has is dependent upon the location of the fulcrum, resistance, and the force in relation to each other. O all of the above are true
