GATE Mechanical Engineering (ME) 2019 Shift 2 Solved Paper

The state of stress at a point in a component is represented by a Mohr's circle of radius $100\mathit{M}\mathit{P}\mathit{a}$ centered at $200\mathit{M}\mathit{P}\mathit{a}$ on the normal stress axis. On a plane passing through the same point, the normal stress is $260\mathit{M}\mathit{P}\mathit{a}$. The magnitude of the shear stress on the same plane at the same point is ______ Mpa.
