Polar moment of inertia of a circle1/3/2023 ![]() ![]() The magnitude of the electric field inside the cylinder is: It carries a surface charge density σ0cosφ, where φ is the polar angle and σ0 is a constant. Polar molecules are the molecules (1) Having a permanent electric dipole moment (2) Having zero dipole moment (3) Acquire a dipole moment only in the presence of electric field due to displacement of charges (4) Acquire a dipole moment only when magnetic field is absentĪn infinitely long thin cylindrical shell has its axis coinciding with the z-axis. The magnitude of the shear stress on the same plane at the same point is _ MPa. On a plane passing through the same point, the normal stress is 260 MPa. The state of stress at a point in a component is represented by a Mohr’s circle of radius 100 MPa centered at 200 MPa on the normal stress axis. Moment of inertia of a thin rod of length ‘a’ and mass 'm’ about an axis passing through an end and perpendicular to the rod is given by The point, though which the whole weight of the body acts irrespective of its position is known as ![]() ![]() If the pitching moment (M) derivative with respect to angle of attack (α), denoted by ‘Mα’, is -0.504 N-m/rad and the pitching moment (M) derivative with respect to pitch rate (q), denoted by ‘Mq’, is -0.0336 N-m/(rad/s), the damping ratio of the resulting motion due to an initial disturbance in pitch angle is approximately _ (accurate to three decimal places). The gyroscopic moment exerted by the rotor on the aircraft structure and the direction of motion of the nose when the aircraft turns, areĪn aircraft wind tunnel model, having a pitch axis mass moment of inertia (Iyy) of 0.014 kg-m^2, is mounted in such a manner that it has pure pitching motion about its centre of gravity, where it is supported through a frictionless hinge. The aircraft while flying at a speed of 800 km per hour takes a turn with a radius of 1.5 km to the left. The rotor rotates at a constant speed of 1100 rad/s in the clockwise direction when viewed from the front of the aircraft. The rotor of a turbojet engine of an aircraft has a mass 180 kg and polar moment of inertia 10 kg Find its moment of inertia about its diameter. The moment of inertia of a solid sphere about a tangent is 2/5 MR^2. ![]() Moment of total area about its centroidal axis is: VTU SYLLABUS 2010 STRENGTH OF MATERIALS (COMMON TO CV/TR/EV/CTM) Engineering.ĬG and Visualisation Lab(10CSL67) Vtu prg-4ĬG and Visualisation Lab(10CSL67) Vtu prg-3ĬG and Visualisation Lab(10CSL67) Vtu prg-6 The polar moment of inertia of a circle about its centroidal axis is 1 Point NotesĬG and Visualisation Lab(10CSL67) Vtu prg-8 ![]()
