Textbook Question

Chapter 12.1, Problem 12.50P

A 55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. Knowing that the plane has a speed of 550 km/h at point A, and the pilot experiences weightlessness at point C (i.e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point B.

The crate/box shown has a square shape, an in-plane size of 10 ft X 10 ft and a uniformly distributed 300 lb weight. It is hung on an overhead roller conveyer and being transported. The crate is at rest when a horizontal force P of 40 lb is applied at the point E, which is 4 ft above the bottom of the box. Knowing that the crate starts to move from rest and at the instant t it reaches a speed of 9.3 ft/s. Neglect the frictions at the hinges A and B and between the rollers and the rail track. Answer the following questions: a) Draw FBD and KD of the box. b) What kind of motion the crate is moving in? c) Write out the motion equations. d) Find the acceleration at the crate's mass center and the pin forces at A and B. e) Determine the distance d and time t of the motion when the speed reaches 9.3 ft/s. A B P 10 ft E 4 ft D + 10 ft

Slider C has a mass of 0.5 kg and may move in a slot cut in arm AB, which rotates at constant speed in a horizontal plane. The slider is attached to a spring of constant k = 150 N/m, which is unstretched when r = 0. When arm AB rotates about the vertical axis, the slider moves without friction outward along the smooth slot cut. Determine for the position r = 80 mm: a) The constant speed (V) of the slider. b) The normal force (N) exerted on the slider by arm AB. A r=80mm B

A 4-kg collar A is at rest on a spring with stiffness k1 = 310 N/m, but the spring is not connected to the collar, when a force F of 220 N is applied to the cable. Knowing that A has a speed of 0.5 m/s when the upper spring is compressed 75 mm, determine the stiffness k2, in N/m ignore friction and pulley mass 450 mm peper 75 mm - 400 mm- F
