A cantilever beam ofcross section area ‘A’, moment of Inertia ‘I’ and length ‘L’ is having
natural frequency $$\omega 1$$. If the beam is accidently broken into two halves, the natural
frequency of the remaining cantilever beam $$\omega 2$$ will be such that

In CAD, the geometric transformation is expressed as P * = [T]P where T is the transformation matrix. If the matrix T is diagonal, then the transformation is called

A water tank is located 3 m above ground and depth of water in tank is 2 m. Exit pipe is 50 mm in dia and 50 m long. Velocity of water at the exit at the ground level is approximately (Take friction factor f = 0.05, g = 10 m/s$$^2$$)

The work ratio of a gas turbine is a function of

The distribution of temperature T, at a particular instant, across a large concrete wall, 1 m thick, which is heated from one sideis given by the equation $$T = 150 - 80x + 16x^2$$, where the distance x is in meters and Tis in degree Celsius. Thermal conductivity of wall is 0.6 W/mK, area of cross section is 10 m?. The heat accumulated in unit time at this instant in the concrete wall is —
