Suppose you use a machine that gives you a mechanical advantage of 2 to achieve an output force of 30 newtons. what must the input force be? 15 n20 n40 n60 n

The correct answer is 15 N.

Explanation:

The mechanical advantage of a machine is calculated as,

M.A = Output Force/ Input Force

Given, mechanical advantage=2

Output force = 30 N

Substituting the values,

Input force = 15 N

∴ The input force must be 15 N.

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
