Question:
Which of the following is not a way that machines provide a mechanical advantage?
a. change direction
b. change distance
c. change power
d. chance force
a. change direction
b. change distance
c. change power
d. chance force
Answers
B. Change distance.
Distance is fixed and cannot be changed. The distance from A to B depends on the route you decide to take. There is no machine that can change "distance".
i just took the test, A is incorrect.
im guessing its C, but not certain
option b
Explanation:
A machine makes work easy. It either changes direction, changes power or force. The mechanical advantage measures the amount of force increased over the applied one.
[tex]MA=\frac {F_o}{F_i}[/tex]
The mechanical advantage helps to assess the working of a machine.
A machine does not change distance of the work to be done.
The following choice that is NOT a way that machines provides a mechanical advantage is to change direction. The correct answer is A.
