A wheel of radius R=10 cm and moment of inertia I=0.05kg m^(2) is rotating about a fixed horizontal axis O with angular velocity omega_(0)=10rads^(-1) . A uniform riigid rod of mass m=3 kg and length l=50 cm is hinged at one end A such that it can rotate at end A in a vertical plane. End B of the rod is tied with a thread as shown in figure such that the rod is horizontal and is just in contact with the surface of rotating wheel. Horizontal distance between axis of rotation O of cylinder and A is equal to a = 30 cm . If the wheel stops rotating after one second after the thread has burnt, calculate coefficient of friction , mu between the rod and the surface of the wheel. (g = 10 ms^(-2))

Two blocks A and B having mass m = 1 kg and M = 4 kg respectively are attached to a spring and placed vertically on a weighing machine as shown in the figure. Block A is held so that the spring is relaxed. A is released from this position and it performs simple harmonic motion with angular frequency w = 25 rad s^(-1) . The spring remains vertical (a) Find the reading of the weighing machine as a function of time. Take t = 0 when A is released. (b) What is the maximum reading of the weighing machine ?

A small spherical marble of mass m and radius r is rolling without slipping on a rough track with speed v.The track further is in the shape of a vertical circle of radius R as shown in figure-5.144. With what minimum linear speed the marble is rolling so that it completely goes round the circle on the circular part of track.

STATEMENT-1: One end of a string of length r is tied to a stone of mass m and the other end to a small pivot on a frictionless vertical board. The stone is whirled in a vertical circle with the pivot as the centre. The minimum speed the stone must have, when it is at the topmost point on the circle, so that the string does not slack is sqrt( gR) . because STATEMENT-2: At the topmost point on the circle, the centripetal force is provided partly by tension in the string and partly by the weight of the stone.

A thin pencil of mass M and length L is being moved in a plane so that its centre (i.e. centre of mass) goes in a circular path of radius R at a constant angular speed omega . However, the orientation of the pencil does not change in space. Its tip (A) always remains above the other end (B) in the figure shown (a) Write the kinetic energy of the pencil. (b) Find the magnitude of net force acting on the pencil.

A pitot tube Fig. is used to determine the air speed of an airplane. It consists of an outer tube with a number of small holes B (four are shown that allow air into the tube, that tube is connected to one arm of a U-tube. The other arm of the U-tube is connected to hole A at the front end of the device, which points in the direction the plane is headed. At A the air becomes stagnant so that v_(A) = 0. At B, however, the speed of the air presumably equals the airspeed v of the plane. (a) Use Bernoulli's equation to show that v = sqrt((2rho gh)/(rho_(air))) where rho is the density of the liquid in the U-tube and his the difference in the liquid levels in that tube. (b) Suppose that the tube contains alcohol and the level difference h is 20.0 cm. What is the plane's speed relative to the air? The density of the air is 1.03 kg//m^(3) and that of alcohol is 810 kg/ m^(3)
