In transportation It is not necessary square matrix. but in assignment it is necessary to have square matrix.
Total supply must equal to total demand in the transportation problem,but each supply and demand value is 1 in the assignment problem.
there is nothing like a balanced and unbalanced transformer.
Unbalanced forces don't add up to zero. Balanced forces do.
Unbalanced forces don't add up to zero. Balanced forces do.
Unbalanced forces is when the forces are 0N or more. Balanced forces are 0.
Railroad transportation is by train, and water transportation is by boat.

Transportation barrier means transportation if barred - not allowed. Transportation corridor means transportation is allowed.
Cars = ground transportation Airplanes = air transportation
The assignment would be a comparison/contrast assignment.
Balanced force means that the sum (vector sum) of all forces on an object is zero. Unbalanced means it's not.
