Acceleration due to gravity g=9.8ms2. Which of the following is/are correct?
A pulley system has velocity ratio of 3. If it efficiency is 75%, calculate its mechanical advantage. [Assume 1 kgf = 10N, 1 gf = 1000 dynes]
A pulley system has velocity ratio of 3. If it efficiency is 75%, calculate the maximum load it can raise using an effort of 30 N. [Assume 1 kgf = 10N, 1 gf = 1000 dynes]
