Question

four forces act on bolt Aas shown
Determine the resultant of the
forces on the bolt
F1=80N
F2=150N
F3=100N
F4=110N​

Answer 1

Answer:

440 N is the resultant force

Answer 2

Answer:

199.2N

Explanation:

First resolved all the forces,we get

ΣFx=150cos30°+100cos15°-80sin20°

=198.7N

ΣFy=150sin30°+80cos20°-100sin15°-110

=14.4N

Now,

Resultant Force(R)=√(ΣFx^2+ ΣFy^2)

=199.2N
