Answer:
The magnitude of Resultant force is F = 7.21-lbs
Explanation:
Two forces acting on an object which are named as F1 and F2.
The angle formed by the forces are 60-degrees
F1 = 6-lbs , F2 = 8-lbs
theeta = 60°
F = √F1²+F2²-2(F1)(F2)cos(theeta)
F = √(6)²+(8)²-2(6)(8)cos(60)
F = √36+64-(96)cos(60)
F = 7.21-lbs
where,
F1 = magnitude of force 1
F2 = magnitude of force 2
theeta = angle formed by forces
Answer:
2.21 N
Explanation:
The force in this case is the total mass multiplied by the acceleration due to gravity. You are not asked for the solution to be in terms of the torque which is the usual way to solve these problems. That's why you are not given where the fulcrum is.
The fulcrum feels F1 + F2 + 34 * 980
F2 = 141.7 * 980 = 138866
F1 = 50.3 * 980 = 49294
Ruler = 34 * 980= 33320
Total Force = 221480 The units here are dynes
I just saw in the middle of the question that g = 9.80
So the answer becomes 221480 / 1000 = 221.48 because we needed kg
And that answer becomes 221.48/100 2.21 because the force of gravity should be 9.8 not 980
The total force exerted on the fulcrum is
The constellation is the dependent variable because they depend on the stars to form them.
Stars are independent variables in this case because they do not need constellations to form them.
Constellations are dependent variables in this case because they depend on stars to form them. Constellations are literally a group of stars that make an imaginary picture to us.
