Answer:
a) P ≥ 22.164 Kips
b) Q = 5.4 Kips
Explanation:
GIven
W = 18 Kips
μ₁ = 0.30
μ₂ = 0.60
a) P = ?
We get F₁ and F₂ as follows:
F₁ = μ₁*W = 0.30*18 Kips = 5.4 Kips
F₂ = μ₂*Nef = 0.6*Nef
Then, we apply
∑Fy = 0 (+↑)
Nef*Cos 12º - F₂*Sin 12º = W
⇒ Nef*Cos 12º - (0.6*Nef)*Sin 12º = 18
⇒ Nef = 21.09 Kips
Wedge moves if
P ≥ F₁ + F₂*Cos 12º + Nef*Sin 12º
⇒ P ≥ 5.4 Kips + 0.6*21.09 Kips*Cos 12º + 21.09 Kips*Sin 12º
⇒ P ≥ 22.164 Kips
b) For the static equilibrium of base plate
Q = F₁ = 5.4 Kips
We can see the pic shown in order to understand the question.
Explanation:
These are probably the most used tool in any Plumber’s tool box. Pliers are not just another tool for a Plumber, they become an extension of their arms. Most people think that sounds odd, but pliers are more than just a tool to grab or turn things.
These are probably the most used tool in any Plumber’s tool box. Pliers are not just another tool for a Plumber, they become an extension of their arms. Most people think that sounds odd, but pliers are more than just a tool to grab or turn things.Sometimes a piece of copper pipe won’t quite go into a fitting. By using the handle end as a mallet you can gently force it in without damaging/denting the pipe or fittings. Or, when a brute force is needed the jaw end becomes a hammer. On an old pair of pliers I took a grinder to form one side of the handle into a flathead screwdriver/pry bar.
Answer:
178 kJ
Explanation:
Assuming no heat transfer out of the cooling device, and if we can neglect the energy stored in the aluminum can, the energy transferred by the canned drinks, would be equal to the change in the internal energy of the canned drinks, as follows:
ΔU = -Q = -c*m*ΔT (1)
where c= specific heat of water = 4180 J/kg*ºC
m= total mass = 6*0.355 Kg = 2.13 kg
ΔT = difference between final and initial temperatures = 20ºC
Replacing by these values in (1), we can solve for Q as follows:
Q = 4180 J/kg*ºC * 2.13 kg * -20 ºC = -178 kJ
So, the amount of heat transfer from the six canned drinks is 178 kJ.
Answer:
The required bulk modulus is 
Psi. So, the answer is non of these.
Explanation:
Change in pressure of the fluid is directly proportional to the volumetric strain. The constant of proportionality is the bulk modulus of the fluid.
Step1
Given:
Percentage change in volume is 1%.
Change in pressure is 10000 Psi.
Calculation:
Step2
Volumetric strain is calculated as follows:
Step3
Bulk modulus is calculated as follows:
\frac{\bigtriangleup V}{V}=0.01
K = 1000000 Psi.
Thus, the required bulk modulus is Psi.
