If Rx = ΣFx and Ry = ΣFy, an object is in equilibrium only if:

Rx = Ry
Rx > Ry
Rx = 0 and Ry = 0
R = Rx + Ry

Three forces are F1=6î-8ĵ, F2=-3î+4ĵ, F3=-3î+4ĵ. The object is:

In equilibrium
Accelerating North
Accelerating South
Accelerating East

The term ‘equilibrant’ refers to a force that:

Is the resultant of all forces
Causes an object to accelerate
Brings an object into equilibrium
Is always perpendicular to the resultant

An object is at rest. The net force on it is:

Increasing
Decreasing
Zero
Equal to its mass

If three vectors of equal magnitude can produce equilibrium, they must be arranged at angles of:

90°, 90°, 180°
60°, 60°, 240°
120°, 120°, 120°
45°, 45°, 270°

Forces F1 = (5, 5), F2 = (-10, 5), F3 = (5, -10) act on a point. The resultant is:

(0, 0)
(10, 10)
(0, 20)
(20, 0)

To find a fourth force that produces equilibrium with three known forces, one must find a force that is:

Equal to the resultant of the three forces
Equal in magnitude but opposite in direction to the resultant of the three forces
The average of the three forces
The largest of the three forces

A force F1 = 10 N East and F2 = 20 N West act on a body. A third force F3 is needed for equilibrium. F3 must be:

30 N West
30 N East
10 N West
10 N East

Three forces F1=(10î) N, F2=(-15î) N, and F3=(5î) N are acting on a body. The body is:

Accelerating
In equilibrium
Moving at constant velocity
Both B and C are possible

Three vectors A, B, and C are added by the component method. The x-component of the resultant is:

Ax + Bx + Cx
Ax * Bx * Cx
(Ax+Bx+Cx)/3
√(Ax²+Bx²+Cx²)

Four forces act on a point: 10N North, 20N South, 5N East, 15N West. The resultant force is:

10 N South-West
14.1 N South-West
10 N North-East
14.1 N North-East

If ΣFx = 0 and ΣFy = 0 for a set of forces, the object is in:

Rotational equilibrium
Translational equilibrium
Dynamic motion
Unstable equilibrium

In equilibrium, the sum of the x-components of all forces (ΣFx) is:

ΣFy
Maximum
Minimum
Zero

Given F1=3î+4ĵ and F2=2î-ĵ. A third force F3 is applied to keep the body in equilibrium. F3 must be:

5î + 3ĵ
-5î – 3ĵ
-3î – 5ĵ
3î + 5ĵ

A body is in equilibrium under the action of three forces. The resultant of any two forces is:

Zero
Equal and opposite to the third force
Greater than the third force
Smaller than the third force

Three forces F1=(2,3), F2=(-4,2), and F3=(2,-5) act on a body. The resultant force has components:

(0, 0)
(8, 10)
(-2, 5)
(0, -1)

For a body to be in equilibrium, the sum of all forces acting on it must be:

A large positive value
A large negative value
Zero
Equal to its weight

A vector A has magnitude 5. A vector B has magnitude 12. Their resultant R has magnitude 13. The angle between A and B must be:

0°
45°
90°
180°

The direction of the resultant of two vectors (A and B) is found using the formula θ = tan⁻¹(Ry/Rx). Ry and Rx represent:

The magnitudes of A and B
The components of A and B
The sums of the x and y components, respectively
The products of the x and y components
