Explanation Given: Weight of the ramp is 20 lb , weight of the ballis 15 lb and Falling distance is h . Concept used: Conservation of energy is expressed as follows: E i = E f …… (1) Here, initial energy is E i and final energy is E f . Conservation of momentum is expressed as follows: P i = P f …… (2) Here, initial momentum is P i and final energy is p f . Calculation: Substitute m s v o × r + 0 for P i and m s v r + m r r 2 2 ω + m r ω r 2 for P f in equation (2). m s v o × r + 0 = m s v r + m r r 2 2 ω + m r ω r 2 ω = m s ( v o − v ) 3 2 m r r Substitute 1 2 m s v o 2 + 0 for E i and 1 2 m s v 2 + 1 2 I ω 2 + 1 2 m r ( ω × r ) 2 for E i in equation (1). 1 2 m s v o 2 + 0 = 1 2 m s v 2 + 1 2 I ω 2 + 1 2 m r ( ω × r ) 2 1 2 m s v o 2 + 0 = 1 2 m s v 2 + 1 2 × m r × r 2 2 ω 2 To determine (b) Velocity of slab after it has moved a distance nb.

Students have asked these similar questions

A gearbox has permanent shaft positions defined by the bearing mounting positions, but the gear ratio can be changed by changing the number of teeth in the pinion and gear. To achieve similar power transmission ability for different gear ratios, a manufacturer chooses to have the same module for two different gearboxes. One of the gaerboxes has a pinion with 22 teeth, a gear with 68 teeth, and a center distance of 225mm. How large is the gear module and which gear ratios are possible for a pinion with 22 or more teeth using the same module?

A gear train has a 50.3 mm circular pitch and a 25 degree pressure angle and meshes with a pinion having 12 teeth Design this gear train to minimize its volume and the total number of teeth. Obtain the pitch diameters the number of teeth the speed ratio the center distance and the module of this gear train. The gearbox housing has a diameter of 620mm
