A uniform thin rod of mass M and length L is supported horizontally by two supports one at each end. The acceleration of gravity g is constant and in the downward direction At time t=0 the left support is removed Normal force on the right support immediately after the left support is removed is `(Mg)/(x)`.Fill x

A uniform rod of mass m and length l is held horizontally by two vertical strings of negligible mass, as shown in the figure. (a). Immediately after the right string is cut, what is the linear acceleration of the end of the rod? (b). Of the middle of the rod? (c). Determine the tension in the left string immediately after the right string is cut.

A uniform beam of length L . And mass m is supported as shown. Of the cable suddenly breaks, determine , (a) the acceleration of end B . (b) the reaction at the pin support. .

A rod of mass m is supported by string AB and friction due to wall. Then friction force on rod due to wall is : (g= acceleration due to gravity )

A horizontal metallic rod of mass 'm' and length 'l' is supported by two vertical identical springs of spring constant 'k' each and natral length l_(0) A current 'l' is flowing in the rod in the direction shown if the rod is in equilibrium then the length of each spring in this state is:

A uniform string of length 10 m is suspended from a rigid support A short wave pulse is introduced at its lowest end it starts moving up the string the time taken to reach the support is (take g=10m//sec^(2) )
