QUESTION:
Determine the magnitude of force F so that the resultant \(F_R\) of the three forces is as small as possible. What is the minimum magnitude of \(F_R\)?
ANSWER:
Step 1 of 4
Since the resultant is the vector sum of all forces acting on the pin we need its magnitude. We can get its magnitude by using the Pythagorean theorem but first we have to express (horizontal) and y (vertical) components of force .
Lets sum up all forces acting in the direction:
and sum of all forces acting in the direction:
