streess is tensor,then,what is meant by tensor?
Tensors are used to represent the relation between vectors. They are geometrical objects which show’s the relation between vectors, vectors and scalars.It is a geometrical maping of the relations .Tensor analysis ,a branch in mathematics is helping to solve the complex equations in which many vectors are involved

Two skaters, one with Mass 45kg, 2′nd with Mass of 65kg stand on an ice rink holding a pole with L=10m with negligible mass. starting from the ends of the pole, the skaters pull themselves along the pole until they meet. How far does the 45kg skater move?
Hint: They will meet at the centre of mass of the system.
If the 45 kg skater moves by x m, then the second one travels (10-x)m
45 x = 65(10-x)
Solve and get the value for x
