A stop block, s, prevents a crate from sliding down a = 35.0 incline. (Figure 1) A tensile force F= (Fot) N acts on the crate parallel to the incline, where Fo=295 N/s. If the coefficients of static and kinetic friction between the crate and the incline are = 0.330 and μ = 0.190, respectively, and the crate has a mass of 42.6 kg, how long will it take until the crate reaches a velocity of 3.68 m/s as it moves up the incline? Express your answer numerically in seconds to three significant figures. View Al

Q5/ In vehicle suspension design it is desirable to minimize the mass of all components. You have been asked to select a material and dimensions for a light spring to replace the steel leaf-spring of an existing truck suspension. The existing leaf-spring is a beam, shown schematically in the figure. The new spring must have the same length L and stiffness S as the existing one, and must deflect through a maximum safe displacement 8max without failure. The width b and thickness t are free variables. L Load F 6= 1 FL³ 48 EI 10₂L² 6 #E 1=bt³/12 8max = Derive a material index for the selection of a material for this application. Note that this is a problem with two free variables: b and t; and there are two constraints, one on safe deflection 8max and the other on stiffness S. Use the two constraints to fix free variables.
