The formula for true strain after derivation from basic terms is; ε_t = In(1 + ε_e)
<h3>How to derive the expression for True Strain?</h3>
Formula for Engineering Stress is;
σ_e = Load/Area
Formula for true stress is;
σ_t = Force/Instantaneous Area
Formula for Engineering Strain is;
ε_e = ΔL/L₀
Formula for true strain is;
dε_t = dL/L
Total true strain is gotten from;
ε_t = ∫(dL/L) between boundaries of L_f and L_o
When we integrate between those boundaries, we have;
ε_t = In[(L₀ + ΔL)/L₀
⇒ ε_t = In[(1+ ΔL/L₀)
⇒ ε_t = In(1 + ε_e)

Answer:
The energy in kJ is 8558.16 kJ.
Explanation:
Data presented in the problem:
Water is heated from 70 (T1) to 200 °F (T2).
Volume (V) of the water is 1 ft3.
It is required for the specific heat of water(HW), which is 1 BTU/lb°F.
First, we need to calculate the mass of water (M) presented in the process. Water density (D) is 62. 4 lb/ft3.
M = V*D = (1ft3)*(62.4 lb/ft3) = 62.4 lb Water.
.After that, we can calculate the heat required (Q).
Q = M*HW*(T2 - T1) = (62.4 lb)*(1 BTU/lb°F)(200 °F - 70°F)
Q = 62.4 * 130 BTU = 8112 BTU.
Q is converted to kJ units using the conversion factor 1 BTU = 1.055 kJ
Q = 8112 BTU * (1.055 kJ/1BTU) = 8558.16 kJ.
Finally, the energy required is 8558.16 kJ.
Answer:
Denial is a defense mechanism which allows an individual not to accept the truth about a painful experience or distress.
Explanation:
Denial is a way of coping with distress. Denial means trying to reject the truth about a situation. It could be denying the truth about your personal situation or about someone else like your friends, parents or siblings.
Denial is a defense mechanism used to protect oneself against accepting a painful experience or situation in life.
Denial could be helpful or harmful.
It can be helpful when one begin to take action about a problem by seeking for help.
It could be harmful if you don't seek for help when in distress.
A person engaged in denial is trying to stay sane and act normal like everything is alright with he/she. The person tries to block negative thought and focus on more positive thoughts.
Example of denial
1) A young lady who just experienced a breakup from her boyfriend who she truly loves but act like the breakup doesn't affect her or that she doesn't love the guy.
2) A 21 year old person who has cancer and has about 10 months to live have plans of celebrating his/her 25th birthday in a big way
3) When someone is harboring the thought that coronavirus is not real or it is not a serious disease.
