Answer:
33.4
Explanation:
Step 1:
\sumMo=0 (moment about the origin)
Fb(15)-Fc(15)=0
Fb=Fc
Step 2:
\sumFx=0
-Fb-Fccos\theta+Ncsin\theta=0
Fc=0.3Nc=Fb
-0.3Nc-0.3Nccos\theta+Ncsin\theta=0
(-0.3-cos\theta+sin\theta)Nc=0----(1)
\sumFy=0
Nccos\theta+Fcsin\theta-Nb=0
Nccos\theta+0.3Ncsin\theta-Nc=0
Nc[cos\theta+0.3sin\theta-1]=0--------(2)
Solving eq (1) and eq (2)
\theta=33.4
Step 3:
As the roller is a two force member
2(90-\phi)+\theta=180
\phi=\theta/2
\phi=Tan(\muN/N)-1
\phi=16.7
\theta=2x16.7=33.4
Answer:
1. Parallel circuit
2. Parallel circuit
3. Series circuit
4. Series circuit
5. Parallel circuit
6. Parallel circuit
Explanation:
1. In a parallel circuit, there are multiple paths for current to flow. The path each current takes depends on the resistance of the resistors on that path.
2. In a parallel circuit, current splits up into various paths to get the total current through the circuit, the current flow through each resistor is added.
3. In a series circuit the voltage across each resistor is not the same. to get back the total voltage, the voltages across each resistor needs to be added.
4. Series circuits have voltage drops across each resistor. this makes the voltage across each resistor depend on the resistance of the resistor.
5. In parallel circuits voltage is the same across each resistor because they are all connected directly to the same source.
6. In parallel circuits, the power is the same in each resistor of equal resistance since the voltage across each resistor is the same

Explanation:
The detailed steps is as shown in the attached file.
Answer:
= 2.6906 × 
lb-s/in²
Explanation:
given data
velocity V = 64 in/sec
separated by a gap x = 0.41 in
relative motion by shear stress 
= 0.42 lb/in²
solution
we know that shear stress is directly proportional to rate of change of velocity as per newton's law of viscosity.
....................1
so here coefficient of dynamic viscosity and 
is velocity gradient
and
put here value and we get
0.42 = 
= 2.6906 × lb-s/in²
