See all →- What are tangential and normal components of acceleration in curvilinear motion? In one line On a curved path, acceleration splits into a tangential part that changes speed and a normal part, towards the centre of curvatu... 1
- How do you find the radius of curvature of a particle's path from its x and y motion? In one line Split the acceleration into tangential and normal parts using the velocity direction, then use ρ = v²/a_n . Explained simply The... 1
- What is general plane motion of a rigid body and how does it differ from translation and rotation? In one line General plane motion is the combination of translation and rotation of a rigid body in a plane, like a rolling wheel or a connec... 1
- What is the instantaneous centre of rotation (ICR) and how is it located? In one line The ICR is the point, in or outside the body, that has zero velocity at a given instant, so the body seems to rotate purely abou... 1
- How is the ICR method applied to a wheel rolling without slipping? In one line For rolling without slipping, the contact point with the ground is the ICR, so every point's velocity equals ω times its distanc... 1
- How do you use the ICR method for a crank and connecting rod (two-link) mechanism? In one line Use the crank's known rotation to get the velocity of the crank pin, then locate the connecting rod's ICR from the crank-pin and... 1
