The Mohr’s circle for an area is helpful so as to_Ī) Determine Minimum moments of inertia for an Areaī) Determine Maximum moments of inertia for a LineĬ) Determine Minimum moments of inertia for a Volumeĭ) Determine Maximum moments of inertia for a RectangleĬlarification: The Mohr’s circle is important as to know what is the maximum and the minimum moment of inertia of an area.
This is the graphical method of solving the moment of inertia of the structures.ġ2. This is because they are the derived quantity from the variables. (Iu – a) 2 + I 2uv = R 2 this equation is wrong for the calculations of the moments.Ĭlarification: The above equation is true for the calculation of the moments. A use of Mohr circle can also help in determining the direction.ġ1. The total work done is the dot product of force and distance not the cross. The couple moment is produced by two forces, not by a single force. What does the moment of the force measure in the calculation of the Mohr circle’s data for the moments of inertia?Ī) The tendency of rotation of the body along with any axisī) The moment of inertia of the body about any axisĬ) The couple moment produce by the single force acting on the bodyĭ) The total work is done on the body by the forceĬlarification: The moment of the force measures the tendency of the rotation of the body along any axis, whether it be the centroid axis of the body, or any of the outside axis. What is the Imax of the Mohr circle of the structure given below?ġ0. This is the graphical method of solving the moment of inertia of the structures.ĩ. This is because they are the derived quantity from the constants itself. Given equation is wrong for the calculations of the moments.Ĭlarification: The above equation is true for the calculation of the moments. Thus the intensity is not varying parabolically nor is it cubically. Whenever the distributed loading acts perpendicular to an area its intensity varies _ for the determination of the Mohr’s circle for inertia.Ĭlarification: The load intensity is varying linearly in the structures. What are Ix, Iy and Ixy in the equation?ħ. Which of the following is the equation which we get for the graphical solution of the moment of inertia?Ħ. The points of action of the three forces are three.ĥ.
So does is the definition of the three forces members. The difference between the two and the three force members is:Ī) The former is collinear and the latter is parallelī) The former is parallel and the latter is perpendicularĬ) The former is perpendicular and the latter is collinearĭ) The former is acting on two points in the body while the latter is on three pointsĬlarification: The definition of the two force member only defines that the forces are being acted on the two points on the body. The body is sometimes acted by two or three force members and we need to find the Mohr‘s circle for inertia for the same. If the axis and the force are meeting at any point then there is no moment applied by the force.Ĥ. It is the moment of the force acting perpendicular to the direction of the axis of rotation. The tendency of rotation of the body along with axis is also called _ As used for the construction of the Mohr circle.Ĭlarification: The tendency of rotation of the body along with axis also called the torque. It means they are derived from constant values of the structure, thus they become a constant value.ģ. It is dependent on the values of the structure which is constant. This is because they are the derived quantity. What is the radius of the Mohr circle of the structure given below?Ĭlarification: In the above question, Ix, Iy and Ixy are meant to be calculated.
This equation is derived from the equations of the product of area inertia. Thus this equation is used so as to ease the calculations. Which of the following is the equation which we get for the graphical solution of the moment of inertia?Ĭlarification: In the graphical method of solving the moment of inertia of the structures, we have the answer as the driven equation.
