The tension in the bicep for the given weight of barbell been supported by the hand is 450 N.

According to Newton's third law of motion, action and reaction are equal and opposite.

When the barbell is held, its weight acts downwards while the force exerted by the bicep pulls the barbell upwards.

A sketch of the force diagram is presented below;

                                                 ↑ Tension in the bicep

                                                 ↑

                                                ⊕

                                                 ↓

                                                 ↓ force of the barbell

Tension in the bicep = force of the barbell

Tension in the bicep = 450 N

Thus, the tension in the bicep for the given weight of barbell been supported by the hand is 450 N.
