Two students pull the dynamometer spring in opposite directions. The first student develops a force of 300N, the second – 200N. Dynamometer reading equals ..
The dynamometer reading will be the result of the forces of the two students. Because two forces are applied to the body (dynamometer) directed along one straight line in opposite directions, then when F1> F2 their resultant will be according to the formula: F is equal. = F1 – F2. Let F1 = 300H, and F2 = 200H, then F is equal. = 300H – 200H = 100H.
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.
