Question
In Fig. 6-34, blocks A and B have weights of 50 N and 20 N, respectively.
(a) Determine the minimum weight of block C to keep A from sliding if ?s between A and the table is 0.21.
(b) Block C suddenly is lifted off A. What is the acceleration of block A if ?k between A and the table is 0.13?
In Fig. 6 - 34, blocks A and B have weights of 50 N and 20 N, respectively. (a) Determine the minimum weight of block C to keep A from sliding if ?s between A and the table is 0.21. (b) Block C suddenly is lifted off A. What is the acceleration of block A if ?k between A and the table is 0.13?Explanation / Answer
a) to prevent from sliding 20 =0.21(50+Mc) hence Mass of C =45.24 N b)if block C is suddenly lifted then 20-0.13*50 =(20+50)a/9.8 hence a = 1.89 m/s^2
