Final answer:
Increased stress on a bone will cause the deformation of the bone to increase. Decreasing the deformation of the bone, the Young's Modulus, the force applied to the bone, or the cross-sectional area where the force is applied will all result in a decrease in stress on the bone.
Step-by-step explanation:
Increased stress on a bone will cause the deformation of the bone to increase. This is because stress is the force applied to the bone per unit area, and increasing the stress will result in a greater force acting on the bone. Decreasing the deformation of the bone, the Young's Modulus, the force applied to the bone, or the cross-sectional area where the force is applied will all result in a decrease in stress on the bone.
The stress on a bone will increase if the cross-sectional area where the force is applied is decreased. Stress is defined as the force per unit area (F/A) acting on an object. A smaller cross-sectional area with a given force leads to greater stress. This is because stress is inversely proportional to the area over which the force is distributed. Decreasing the force applied, decreasing the deformation, or increasing Young's Modulus would all decrease the stress on the bone, not increase it.
