Question

Чему равен коэффициент жесткости стержня, если под действием груза 800 Н он удлинился на 0,8 мм?

Answer 1

Ответ:

10⁶ Н/м

Объяснение:

F=800 H    x=8*10⁻⁴ м    k=?

===

F=k*x ----> k=F/x=800/(8*10⁻⁴)=10⁶ Н/м

Answer 2

Coefficient of Rigidity of a Rod

To determine the coefficient of rigidity of a rod, we need to know the force applied to the rod and the resulting elongation. In this case, the force applied to the rod is 800 N and the elongation is 0.8 mm.

The coefficient of rigidity, also known as the shear modulus or modulus of rigidity, is a measure of a material's resistance to shearing deformation. It is denoted by the symbol G.

To calculate the coefficient of rigidity, we can use the formula:

G = (F * L) / (A * ΔL)

Where: - G is the coefficient of rigidity - F is the force applied to the rod - L is the original length of the rod - A is the cross-sectional area of the rod - ΔL is the change in length of the rod

Unfortunately, the search results provided do not contain the necessary information to calculate the coefficient of rigidity for the given scenario. Therefore, I am unable to provide a specific value for the coefficient of rigidity in this case.

If you have any additional information about the rod, such as its material or cross-sectional area, I would be happy to assist you further in calculating the coefficient of rigidity.
