Zero.
Forces combine as vectors.
The magnitude of the resultant force is equal to the sum of the magnitudes of the two combining forces only when the forces are parallel.
Caveat: This does assume that the "maximum result" desired is a single force, such as would be relevant in producing the linear acceleration of a mass. If, for instance, one wanted to produce the maximum torque as a "result," the points (locations) where the forces were applied would make a difference and there are circumstances where torque would be maximized by oppositely directed forces.

A group of forces is an unbalanced group when the vector sum of all the forces in the group is not zero. It's not the forces that are unbalanced. It's the group.
the sum of all forces acting on an object should be equal to zero the sum of all forces acting on an object should be equal to zero
You should point it at a 40 degree angle.
Why should there be a maximum? If there is friction, ALL the mechanical energy will eventually be converted to heat.
should be should be
between 45min and 2 hours
Hot compress should be use 5-10mins. It should alternately do with the cold compress for a better result.

Zero Proof: R2 = P2 + Q2 + 2 P Q cos@ Differentiating with respect to @, we get 0 = 0 + 0 + 2 P Q (-sin @) This is because R is maximum and P and Q are not variables. ===> sin@ = 0 ===> @ = 0

The maximum power of a class 2 power can be between 40-50v. You should always make sure you are aware what is the maximum output for your electronics.
Whenever you both feel that you are ready.
