Question
A box shown in Fig 4-55 lies on an inclined plane tilted at an angle ? to the horizontal. The coefficient of static friction between the box and the inclined plane is 0.35 and the coefficient of kinetic friction between the two surfaces is 0.19. The angle ? is initially zero and gradually increased until the box just begins to slide.(a) Calculate the critical value ?.(The angle at which the box just begins to slide)
(b) Calculate the acceleration of the box at this angle. m/s2
Well I know that part a is 19.29 degrees, however the answer to part b is not zero.
Explanation / Answer
when gsin(theta)=.35 g cos(theta) so tan(theta )=.35 theta =19.2 degrees 2)gsin(19.2)-mu kinetic (g )c0s(19.2)
