# The weight of a simple mechanism and the friction in it are negligible. If using this mechanism

The weight of a simple mechanism and the friction in it are negligible. If using this mechanism we win 5 times in strength, then we … A) we lose 5 times in distance B) We win 5 times in distance C) we lose 25 times in distance D) We win 25 times in distance once

With regard to any simple mechanism, the following formula works: A = F * S, where F is the force applied to a certain point; S is the distance traveled.

1) Let the initial force be equal to F, then the work done by the mechanism is equal to A1 = F * S1.

2) After increasing the applied force by 5 times, substitute 5 * F into the work formula: A2 = 5 * F * S2.

3) If A1 = A2, F * S1 = 5 * F * S2.

4) From the formula we express S2 = F * S1 / 5 * F = S1 / 5.

That is, judging from the formula obtained, with an increase in force F by 5 times, the loss in distance is also 5 times. One of the components of a person's success in our time is receiving modern high-quality education, mastering the knowledge, skills and abilities necessary for life in society. A person today needs to study almost all his life, mastering everything new and new, acquiring the necessary professional qualities.
