Explanation:
Given that,
Angle by the normal to the slip α= 60°
Angle by the slip direction with the tensile axis β= 35°
Shear stress = 6.2 MPa
Applied stress = 12 MPa
We need to calculate the shear stress applied at the slip plane
Using formula of shear stress
Put the value into the formula
Since, the shear stress applied at the slip plane is less than the critical resolved shear stress
So, The crystal will not yield.
Now, We need to calculate the applied stress necessary for the crystal to yield
Using formula of stress
Put the value into the formula
Hence, This is the required solution.

If a 3 Ω and a 1.5 Ω resistor are wired in parallel and the combination is wired in series to a 4 Ω and a 10 V emf device then the current in the 3 Q resistor is 0.667 Ampere
<h3>What is resistance?</h3>
Resistance is the obstruction of electrons in an electrically conducting material.
The mathematical relation for resistance can be understood with the help of the empirical relation provided by Ohm's law.
V=IR
As given in the problem 3 Ω and a 1.5 Ω resistor are wired in parallel
Their equivalent resistance would be
1/Re= 1/R1 + 1/R2
1/Re = 1/3 +1/1.5
Re= 1 Ω
Now this parallel equivalent is connected with a series combination with a 4Ω resistor
For calculating equivalent resistance in series combination.
R = R1 + R2
R = 1 + 4
R = 5 Ω
As the 10 V emf device is connected then the current flowing can be calculated by using Ohms law
V=IR
10 = 5×I
I = 2 ampere
as the voltage is divided between parallel resistor combination and series resistor
The voltage drop across parallel combination = 10×(1/1+4) volt
= 2 volt
Now the current flows through a 3 Ω resistor by using Ohms law
I = V/R
I= 2/3
I = 0.667 Ampere
Thus, the current flowing through the 3 Ω resistor comes out to be 0.667 Ampere
