Answer ALL parts (a) - (c) The dynamic pressure in GPa from a gas explosion on the ceiling of a room can be estimated by P(t) = 86te-2, where is the number of seconds since the explosion. (a) Find when the pressure will reach its peak value. (b) Calculate the value of the maximum pressure. (c) Use Newton's method to calculate when the pressure will fall to the half of the peak value. Start from a guess time that is greater than the time calculated from (a) and stop after you have completed ed 2 rounds of iteration. 2. (d) Sketch the pressure curve as the function of time and use the curve to explain what would happen if the chosen guess time were smaller than the time calculated from (a). Answer ALL parts (a) - (c) A one degree of freedom damped mass-spring system is subjected to an impulse load. The dynamic equilibrium equation of the system is below 4x(t) + 2#xl} + x(t) = u(t) — u(t – 3) dt² dt Where x(t) is the displacement of the mass at time t, u(t) and u(t− 3) are two step (Heaviside) functions of time. (A.1) (a) Draw a graph of the impulse force u(t)-u(t-3) and state what is the duration of the impulse. (b) Assume the initial displacement and initial velocity are all zero, (1) Find the Laplace Transfer of the displacement of the system (show workings) (2) Find the displacement as a function of time using inverse Laplace transform (show workings) (hint: L[x(t-a)u(ta)] = e-sax(s) may be used in the inverse Laplace Transform)

Moving to another question will save this response. Question 1 Which of the following statement is NOT correct? Fluid Mechanics is the study of the behaviour of fluids. Fluid Mechanics is the study of the behaviour of solids. Fluid Mechanics is the study of the behaviour of liquids. Fluid Mechanics is the study of the behaviour of gases.

Write legibly and box the final answer

I need answer within 5 minutes please please with my best wishes

I am attaching both questions for 4 and 5 with the question in the image. thank you. NOTE : So the last person answered this question WITHOUT refencing the answer for whether question 4 or 5 answeres were given, so i am asking for question 5(or the answer for the question that was NOT solved because it was not referenced.) These were the following answers given to me from the last person on bartleby who answered my question without referencing whether it was the answer for question 4 or 5.  1 pass 2 fail 3 fail 4 pass

follow up question - for the past two question. (subquestions)

HANDWRITTEN. answer 4 5 6 then box the final answers

How did you get 4/5 and 3/5?

hi please solve this dof question

Could you please spreate each question alone because there are two questions
