Problem # 2 Example: A Lifting Eye
Two ropes are attached to this lifting eye. Force A is
1200N at 75°, and Force B is 1600N at 60° from
horizontal
What is the RESULTANT of these two forces?
60

0.55x745.7j and a calculator

the bal will not change its velocity.

weight of the box is given as

here this is placed on the inclined of angle 42 degree

now this weight will have two components one is along the incline other is perpendicular to it

so here we need to apply a force parallel to incline opposite to its component of weight

so here the component of weight is given as

here we have

so it requires 75 n force to move it upwards
