Question: QUESTION 1(a) Explain with the aid of diagram of a mass-pulley system, the kinematics of a dependent motion and state the assumption(s) for the kinematic analysis.(COI/C2/5 marks)(b) Pin A moves along the fixed ...
System of Object-Pulley and String: When two objects of different mass connect with a string and hang with the help of a pulley, the heavier mass will decide the direction of the object's motion. The heavier mass tries to move downward, whereas the lighter mass will move upward. ...
The invention discloses a test method for an indicator diagram of a belt-type and chain-type pumping well. In operation of the pumping well, borne load data of bearing pedestals at two ends of a rotating shaft supporting a roller or a crowned pulley are tested by a load sensor; rotation...
