To solve the problem, we will use the principle of moments (torque) which states that for an object to be in equilibrium, the clockwise moments about a pivot point must equal the counterclockwise moments. ### Step-by-Step Solution: 1. **Identify the Given Data:** - Length of the nut cutter (lever arm) = 15 cm - Force required to break the nut without the cutter = 22.5 kg - Force applied with the cutter = 2.25 kg ...

ABC is a light pipe lying in a vertical plane and of cross sectional area 1 cm^(2) whose small part is in ground to fix the pipe. An ideal fluid of density 10 ^(4) kg//m^(3) is being flown through the pipe by means of external agency. Length of BC can be neglected. The minimum vertical upward force required to pull out the pipe from ground is F=9N . What should be maximum velocity (in m//s ) of the fluid so that pipe can not be pulled out from ground ?

Two thin circular disks of mass 2kg and radius 10 cm each are joined by a rigid massless rod of length 20 cm. the axis of the rod is along the perpendicular to the planes of the disk through their centres. This object is kept on a truck in such a way that the axis of the object is horizontal and perpendicular to the direction of the motion of the truck. Its friction with the floor of the truck is large enough so that the object can roll on the truck without slipping. Take x axis as the direction of motion of the truck and z-axis as the vertically upwards direction. if the truck has an acceleration of 9m//s^2 Calculate: (i) The force fo friction on each disk, (ii) The magnitude and the direction of the frictional torque acting on each disk about the centre of mass O of the object. Express the torque in the vector form in terms of unit vectors hati, hatj and hatk in the x,y, and z directions.
