Answer:
The force exerted by the biceps is 143.8 kgf.
Explanation:
To calculate the force exerted by the biceps, we calculate the momentum in the elbow.
This momentum has to be zero so that her forearm remains motionless.
Being:
W: mass weight (6.15 kg)
d_W= distance to the mass weight (0.425 m)
A: weight of the forearm (2.25 kg)
d_A: distance to the center of mass of the forearm (0.425/2=0.2125 m)
H: force exerted by the biceps
d_H: distance to the point of connection of the biceps (0.0215 m)
The momemtum is:
The force exerted by the biceps is 143.8 kgf.

X - rays are considered an
oxidizing mutagenic agent. X-rays are high energy
electrons that can cause damage when exposed under extreme conditions. The best
technology that can block it is t using a lightweight type of metal foam. It
can take in high energy collisions which also exhibits high forces. it does not
only block x-rays but also, neutron radiation and gamma rays.
