A person can lift 45 kg ( ~~100 lb). Using the experimental value of the specific gravity for the metal object 8.50 cgs, how many cubic meters of the metal could the person lift (a) in air, (b) in water? How many actual kilograms of metal is this in air, and in water?

Mass which the person can lift = 45 k g
ρ = 8500 k g / m 3
In air, the man can lift 45 / 8500 m 3
= 0.0053 m 3
In water, there is force of buoyance acting on the body from downwards. So, effectively, the density of the body becomes 8500 1000 = 7500 k g / m 3
So, find the amount of volume like that in the previous case.
In air, it was 45 kgs

When a person stands on tiptoe (a strenuous position), the position of the foot is as shown in Figure (a). The total gravitational force on the body, vector F g, is supported by the force vector n exerted by the floor on the toes of one foot. A mechanical model of the situation is shown in Figure (b), where vector T is the force exerted by the Achilles tendon on the foot and vector R is the force exerted by the tibia on the foot. Find the values of vector T , vector R , and θ when vector F g = 805 N. (Do not assume that vector R is parallel to vector T .)
