We first make equilibrium equations of the body by considering all the three dimensional forces and then the free body diagram is made and solved.
If solving the question in 3D calculations is difficult, then use the 2D system and then equate the total net force to zero, thus the method for solving the work done.
If the body is in equilibrium, but it having a rotational curled ray shown in the free body diagram then:
If the resolved force or the force which you get as the answer after solving the question is negative, then what does this implies?
The net moment of the body is zero that means the work done by the force and the rotational axis is zero.
∑Fx=0, ∑Fy=0 and ∑Fz=0 are vector equations for the three dimensions. They are satisfied when the body is achieved it state of equilibrium, and then the work done is calculated.
Which of the following needs to zero for the perfect equilibrium for the calculation of the work?
The supports in the 3D are having more than three reaction forces. Because they are having three axis on which the components of the work done need to be zero.
If five forces are acting on the single particle and having an angle of 72˚ between each and are collinear, then_____________
Calculate the Normal force developed between the body and the surface due to the work done by the force.
The supports in the 3D are having more than three reaction forces. Because they are having three axis on which the components of the work needs to be zero.
∑Fx=0, ∑Fy=0 and ∑Fz=0 are vector equations for the three dimensions. They are satisfied when the body is achieved it state of equilibrium and the net work done is zero.
Calculate the frictional force developed between the body and the surface due to the work done by the force.
We often determine the work done by the couples. A couple moment is developed when _______ of the attached member is prevented.
What is not the condition for the equilibrium in three dimensional system of axis so as to calculate the unknown forces acting on the body?
