A force vector of -3 Newtons indicates that the force is acting in the opposite direction of the positive direction, with a magnitude of 3 Newtons.
In this case, the mechanical advantage is 1:1 because the output force is equal to the input force. Mechanical advantage is calculated by dividing the output force by the input force. Since they are both 3 N, the mechanical advantage is 1.
In a Class 3 lever, the output force is always less than the input force. This is because the effort force (input force) is situated between the fulcrum and the resistance force (output force). Examples of Class 3 levers include tweezers and human arm muscles.
The resultant of the 6.0-N vertical force and the 3-N horizontal force can be calculated using the Pythagorean theorem. The magnitude of the resultant force would be √(6.0^2 + 3^2) = √(36 + 9) = √45 N. The direction of the resultant force would be the angle θ such that tan(θ) = 3/6, giving θ ≈ 26.6° above the horizontal.
Work is force times displacement (distance). Thus, about 3 work is being done. The unit depends on the unit of the work and distance. If the work unit is Joules, and the distance unit is meters, then the force unit would be Newtons.

the three classification of technology is: tools product process
Racial classifications are groups of physical characteristics. The 3 most common racial classifications, going by bone structures, are Caucasoid, African, and Asiatic.
There are usually 4 classifications: Elliptical, spiral, (including barred spiral), lenticular, and irregular. (However some classifications do have only 3 types.)
