A man will exact the greatest pressure on a bench when he
Answer Details
When a man is standing on a bench, the pressure he exerts on the bench depends on the force he applies and the area of contact between his feet and the bench. The greater the force he applies, the greater the pressure he exerts on the bench. Therefore, the option that exerts the greatest pressure on the bench is when the man stands on the toes of one foot, as this reduces the area of contact between the foot and the bench, leading to a higher pressure. This is due to the fact that pressure is defined as force per unit area, so if the area of contact decreases, the pressure increases for a constant force.
