A metallic rod of mass `20kg` and of uniform thickness rests against a wall while the lower end of rod is in contact with rough floor. The rod makes an angle `60^@` with floor. If the weight of rod produces a torque `150Nm` about its lower end, the length of rod (`g=10 ms^(-2)`)

A rod of length I leans by its upper end against a smooth vertical wall, while its other end leans against the floor. The end that leans against the wall moves uniformly downward. Then:

The end B of the rod AB which makes angle theta with the floor is being pulled with a constant velocity v_(v) as shown. The length of the rod is l .

A uniform ridig rod of mass m & length I is released from vertical position on rough surface with sufficient friction for lower end not to slip as shown in figure. When rod makes angle 60^(@) with vertical then find correct altrnatice/s

A uniform rod is rested on a wall and its lower end is tied wall with the help of a horizontal string of negligble mass as shown. Length of rod is L and height of the wall is h . What will be tension in the string ?

End A of a rod AB is being pulled on the floor with a constant velocity v_(0) as shown. Taking the length of the rod as l , at an instant when the rod makes an angle 37^@ with the horizontal, calculate the velocity of the CM of the rod

A rigid rod leans against a vertical wall (y-axis) as shwon in figure. The other end of the rod is ion the horizontal floor. Point A is pushed downwards with constant velocity. Path of the centre of the rod is

A metal rod of uniform thickness and of length 1m is suspended at its 25cm division with help of a string. The rod remains horizontally straight when a block of mass 2kg is suspended to the rod at its 10cm division. The mass of rod is

A rod of length L is held vertically on a smooth horizontal surface. The top end of the rod is given a gentle push. At at certain instant of time, when the rod makes an angle 37^@ with horizontal the velocity of COM of the rod of 2m//s . The velocity of the end of the rod in contact with the surface at that instant is

A uniform rod of mass M & length L is hinged about its one end as shown. Initially it is held vartical and then allowed to rotate, the angular velocity of rod when it makes an angle of 37^(@) with the vertical is
