Required information NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. Bucket A and block C are connected by a cable that passes over drum B. Drum B rotates slowly counterclockwise and the coefficients of friction at all surfaces are μ = 0.35 and μ = 0.25. Given: W= 120 kg. m B W 30° Determine the smallest combined mass m of the bucket and its contents for which block C will remain at rest. The smallest combined mass m of the bucket and its contents for which block C will remain at rest is 28.896 kg.
