A single-cylinder reciprocating engine has a reciprocating mass of 6 kg. the crank rotates at 60 rpm and the stroke is 32 mm the mass of the revolving parts at 16 mm radius is 4 kg, if two-thirds of the reciprocating parts and the whole of the revolving parts are to be balanced. Determine the balance mass required at a radius of 35 mm and unbalanced force when the crank has turned 50° from the TDC.

A balance has a 5.0kg object at 0.5m from the fulcrum, and a 20.0kg object a certain ways in the opposite direction from the fulcrum. Where would the 20.0kg object need to be for the system to be balanced? Suppose you placed the 20.0kg object at 0.5m away from the fulcrum in the opposite direction of the 5.0kg object. This would result in an unbalanced system. Where could you then place a 10kg object to rebalance the system?
All of the following are TRUE regarding levers EXCEPT O a lever can increase the effect of force application to a body O a lever can increase the speed with which a body can be moved O a lever can increase the distance through which a body can be moved in a given time O the effect a lever has is dependent upon the location of the fulcrum, resistance, and the force in relation to each other. O all of the above are true
