Chapter 14.1, Problem 14.4P

Car A weighing 4000 lb and car B weighing 3700 lb are at rest on a 22-ton flatcar which is also at rest. Cars A and B then accelerate and quickly reach constant speeds relative to the flatcar of 7 ft/s and 3.5 ft/s, respectively, before decelerating to a stop at the opposite end of the flatcar. Neglecting friction and rolling resistance, determine the velocity of the flatcar when the cars are moving at constant speeds.

Students have asked these similar questions

a problem existed at the stocking stations of a mini-load AS/RS (automated storage and retrieval system) of a leading electronics manufacturer (Fig.1). At these stations, operators fill the bin delivered by the crane with material arriving in a tote over a roller conveyor. The conveyor was designed at such a height that it was impossible to reach the hooks comfortably even with the tote extended. Furthermore, cost consideration came into the picture and the conveyor height was not reduced. Instead, a step stool was considered to enable the stocker to reach the moving hooks comfortably. The height of the hooks from the floor is 280.2 cm (AD). The tote length is 54.9 cm. The projection of tote length and arm reach, CB = 66.1 cm. a) What anthropometric design principles would you follow to respectively calculate height, length, and width of the step to make it usable to a large number of people? b) What is the minimum height (EF) of the step with no shoe allowance? c) What is the minimum…

Qu. 5 Composite materials are becoming more widely used in aircraft industry due to their high strength, low weight and excellent corrosion resistant properties. As an engineer who is given task to design the I beam section of an aircraft (see Figure 7) please, answer the following questions given the material properties in Table 3. Determine the Moduli of Elasticity of Carbon/Epoxy, Aramid/Epoxy, and Boron /Epoxy composites in the longitudinal direction, given that the composites consist of 25 vol% epoxy and 75 vol% fiber. What are the specific moduli of each of these composites? What are the specific strengths (i.e. specific UTS) of each of these composites? What is the final cost of each of these composites?please show all work step by step problems make sure to see formula material science
