Answer:
shear strength = 2682.31 Ib/ft^2
Explanation:
major principal stress = 100 Ib / in2
minor principal stress = 20 Ib/in2
Normal stress = 3000 Ib/ft2
<u>Determine the shear strength when direct shear test is performed </u>
To resolve this we will apply the coulomb failure criteria relationship between major and minor principal stress a
for direct shear test
use Mohr Coulomb criteria relation between normal stress and shear stress
Shear strength when normal strength is 3000 Ib/ft = 2682.31 Ib/ft^2
attached below is the detailed solution
Answer:
1.933 KN-M
Explanation:
<u>Determine the largest permissible bending moment when the composite bar is bent horizontally </u>
Given data :
modulus of elasticity of steel = 200 GPa
modulus of elasticity of aluminum = 75 GPa
Allowable stress for steel = 220 MPa
Allowable stress for Aluminum = 100 MPa
a = 10 mm
<em>First step </em>
determine moment of resistance when steel reaches its max permissible stress
<em>next </em>: determine moment of resistance when Aluminum reaches its max permissible stress
Finally Largest permissible bending moment of the composite Bar = 1.933 KN-M
<em>attached below is a detailed solution </em>
Answer:
Ceramics are generally made by taking mixtures of clay, earthen elements, powders, and water and shaping them into desired forms. Once the ceramic has been shaped, it is fired in a high temperature oven known as a kiln. Often, ceramics are covered in decorative, waterproof, paint-like substances known as glazes.
Explanation:
Answer:
Explanation:
Considering the relation of the equilibrium vacancy concentration ;
nv/N = exp (-ΔHv/KT)
Where T is the temperature at which the vacancy sites are formed
K = Boltzmaan constant
ΔHv = enthalpy of vacancy formation
Rearranging the equation and expressing in term of the temperature and plugging the values given to get the temperature. The detailed steps is as shown in the attached file
The demand curve is the graphical representation of the relationship between the price of a good and the quantity demanded for a given period of time.
<h3>What is a demand schedule?</h3>
A demand schedule is a table which shows the quantity demanded of a good or service at different price levels.
A demand schedule can be graphed as a continuous demand curve on a chart where the Y-axis represents the price and the X-axis represents quantity.
Here, a typical representation, the price will appear on the left vertical axis, the quantity demanded on the horizontal axis.
