The Young Modulus, also known as the modulus of elasticity, is a measure of the stiffness of a material. In other words, it is a measure of how much a material will deform when a force is applied to it.
The Young Modulus can be calculated by dividing the stress (force per unit area) by the strain (change in length per unit length) of a material. The equation is E = σ/ε, where E is the Young Modulus, σ is stress, and ε is strain.
Density is a factor in calculating the Young Modulus because it affects the mass of the material, which in turn affects its resistance to deformation. Materials with higher densities tend to have higher Young Moduli and are less likely to deform under a given stress.
The length of a material affects its Young Modulus because it determines the amount of strain that occurs when a force is applied. Longer materials will generally experience more strain and have lower Young Moduli compared to shorter materials.
Hammer pulse time is an important factor in solving the Young Modulus because it represents the duration of the force applied to the material. The longer the hammer pulse time, the greater the force applied and the more strain the material experiences, resulting in a lower Young Modulus.
