A cylindrical rod of steel (E = 207 GPa, 30 * 106 psi) having a yield strength of 310 MPa (45,000 psi) is to be subjected to a l

sineoko [7]

Answer:9.477 mm

Step-by-step explanation:

Given

E=207 GPa

Yield Strength $(s_{yt}) 310 MPa$

load (P)=11,100 N

length of rod(L)=500 mm

$\Delta L=0.38 mm$

we know $\Delta L$ is given by

$\Delta =\frac{PL}{AE}$

where A= cross-section

$A=\frac{11100\times 500}{0.38\times 207\times 10^9}$

$A=70.556\times 10^{-6} m^2$

$A=\frac{\pi d^2}{2}=70.556\times 10^{-6} m^2$

$d=9.477\times 10^{-3} m$

d=9.477 mm

Paula has her own business making cakes for

djverab [1.8K]

Answer:

Since Paula has her own business of making cakes for special occasions, and the total price (P) of one of Paula's cakes is represented by the equation P = 0.75S +10, where S is the number of people the cake serves, for determine what does the 0.75 represent in this situation and what does the 10 represent in this equation, the following mathematical reasoning must be carried out:

P is the price of the cake

S is the number of servings

Therefore, 0.75 is the value of each serving, which can be variable (the number of servings can vary)

In turn, 10 is the fixed cost of each cake.
