PHYSICAL SCIENCE Multiple Choice Which of the following most directly contributes to the actual mechanical advantage always being less than the ideal mechanical advantage:
|
W) the basic design of any machine
|
|
X) friction
|
|
Y) how simple machines are combined
|
|
Z) the input distance always being less than the output distance
|
Explanation:
Detailed explanation-1: -The actual mechanical advantage is the ratio of the output force to the input force. The ideal mechanical advantage is the mechanical advantage in an ideal world. It equals the input distance divided by the output distance.
Detailed explanation-2: -How do we determine the actual mechanical advantage of a machine? We do so by measuring the actual forces involved. Actual mechanical advantage can be calculated by dividing a measured output force by a measured input force.
