... One wire exerts a force of 30.0 N and the other exerts a force of 40.0 N. Determine where to place a third wire and how much force it should exert so that the net force on the tree is zero. • Answer: 50.0 N at 143° from the 40.0 N force ...

Newtons` Second Law
... Newton’s 1st law If the total “resultant” force acting on an object is zero, then the object will either remain at rest or it would move along a line with a constant velocity. ...

... The above condition is sufficient for a point-like object to be at its translational equilibrium. However for an object with size this is not sufficient. One more condition is needed. What is it? Let’s consider two forces equal in magnitude but in opposite direction acting on a rigid object as shown ...

... The idea that the velocity of something used to apply a force is somehow inversely related to how much force is being applied is not an uncommon idea. Imagine that we have a manual transmission car, and we have fixed the accelerator in place about one third of the way to the floor. If the engine is ...

Biomechanics Notes
... Q Angle (angle made by the quadriceps muscle) The quads pull the patella laterally when they fire Women have a bigger Q Angle due to their wider pelvis so women runners tend to have more knee problems than do male runners The gluteus medius attaches to the greater trochanter and it contracts so that ...

... Some Hints: First draw a FBD. Next draw a pseudo FBD where you replace the two angled forces with their x & y component forces. Next calculate the two x & y force components for each of the two tensions. Next realize that the stoplight is at rest in equilibrium, so what does this tell you about the ...
