Two forces, 80N and 100N acting at an angle of 60 degrees with each other, pull on an object. What single force would replace th
KIM [24]

We use the law of Cosines, resultant force

F =\sqrt{(F_{1})^2 + (F_{2})^2 + 2 F_{1} F_{2} cos  \theta   }

Here, (F_{1}) and (F_{2}) are forces acting at angle \theta with each other.

Given F_{1} = 80 N, F_{2} = 100 N and \theta = 60^0.

Substituting these given values in above formula we get

F =\sqrt{(80)^2 + (100)^2 + 2 \times 80 \times 100 \ cos 60^0     } = 156. 20 \ N.

Thus, the resultant force is 156 N.

Hi ) how to do this??
pav-90 [236]

Answer:

X = 12N

Explanation:

Anticlockwise moment = Clockwise moment

Taking the moment at the pivot,

Anticlockwise moment = X×2.0m

Clockwise moment = (2.0N × 4.0m) + (4.0N × 4.0m)

Hence, 2X = (8 + 16)

2X = 24

X = 12N.

I HOPE IT'S OK.
