Question would you help me to find a journal paper which is talking about study different types of chassis frame using finite element analysis and the dimension of chassis frame how to design it.thanks

6.61 A 2.64-kg copper part, initially at 400 K, is plunged into a tank containing 4 kg of liquid water, initially at 300 K. The copper part and water can be modeled as incompressible with specific heats 0.385 kJ/kg · K and 4.2 kJ/kg · K, respectively. For the copper part and water as the system, determine (a) the final equilibrium temperature, in K, and (b) the amount of entropy produced within the tank, in kJ/K. Ignore heat transfer between the system and its surroundings.

Assume that you measured the length of an object as 50 mm using a digital caliber. The measurement was made at 300 + 5 K. What is the actual measurement result? (Resolution of the digital caliber: 0.04 mm, coverage factor: 3, linear thermal expansion coefficients of the digital caliber and the sample are 14*10-6 KP)

The circuit below shows a filter commonly used as the output stage of a power supply. In this application, Vin(t) is switched between 0 and a DC input supply voltage (12V in this case). The filter smooths the switched input so that it is close some desired output from 0-12V. In this exercise, you are interested in determining the start-up behaviour of the system. To this end, do the following: a) Find the transfer function Vout(s) . You may assume that the capacitor and inductor are initially de- Vin(s) energised. b) Att = 0, Vin(t) is switched to 12 V (i.e. Vin(t) = 12u(t)). Find the time response Vout(t) = [-{Vout(s)}. Please use partial fraction expansion and the Laplace Transform table to conduct the inversion(s), showing all of your work and explaining your logic clearly to receive full credit. c) How long will it take for vout (t) to reach 6V? You may use computer tools here, but please clearly explain your logic for full credit. d) Sketch (by hand) the Bode plot for G(s) with the parameter values from part b. As a part of this, please carefully compute and label: i. All asymptotes (e.g. low-frequency & high frequency) All corner frequencies iii. The frequency and magnitude (in dB) of any resonances (if they exist) 50 x 10-3 H 000m 0.25 12 Vin(t) 0.2F 112 Vout(t) Figure 2: System for Question 3
