If the mass of the block is too large and the block is too close to the left end of the bar (near string B) then the horizontal bar may become unstable (i. e., the bar may no longer remain horizontal). What is the smallest possible value of xxx such that the bar remains stable (call it xcriticalxcriticalx_critical)

In positive numbers less than 1, the zeros between the decimal point and non zero are significant
