# Rope and Brain

**Classical Mechanics**Level 4

In the above you can see a rope whose mass is given by the equation *2M^2*(x)*, where M = 1 kg, and x is the distance from point *A*. Find the tension at the string on:-

(1.) Point *B*

(2. ) Point *D*, but for this case x is the distance from point *B*, and below point *B* the mass of the whole string is given by *2M^2*.

(TAKE *g* to be 10ms^-2)

Find Z+ Y ( where Z is the answer for first part and Y for the second one). ( In your final answer which you choose from the options given, dont include 'N')

NOTE : POINT *D* IS THE BASE NOT POINT *A*. THE PICTURE IS INVERTED.
