Problem of finite element analysis(urgent)
Consider the truss system shown in Fig. 2 modelled by three elements. The element numbers are shown in brackets. The node numbers are as indicated in the figure. Suppose that all the trusses have a cross sectional area of A = 0.1 m2 and Young’s modulus E = 70 GPa. Determine the displacements at all the nodes if the force P = 2000 N. The length L = 2 m.

Need this badly today
What work is done on a level track in bringing the velocity of a train weighing 200metric tons from zero to 45 kph, if the frictional resistance at any velocity is 45N/ton, and if the change in speed is accomplished in length of 1000m? (Ans. 26780.95 KN/m)
C. If the track were a 1% upgrade, what would be the additional work to be done?

Moment Area theorem problem. please help
I've been trying to solve the following question for 2 days now and i can't seem to be able to. can someone help me please ?
For the beam shown in Figure 3, the support at A is fully fixed. The beam is tapered however you may consider it to be a beam of 3 varying sections.
Take:
Beam A to B as having 3 times the I value of beam D to end, Beam B to D as having 1.5 times the I value of beam D to end and Beam D to end is 310 UB 46.2 with I = 100 x 106 mm4. Tip: this may be easier to solve using superposition.

Critical points
May answer key po ba kayo nito. Icheck ko lang po sana kung tama answers ko. Thank you po. Critical points/maxima and minima
y=4-6x+x²
y=(2x-1)²
y=2+12x-x³
y=x³-3x²-9x+20
y=x³-3x²+4x+5
y=x³-6x²+12x
y=x⁴+2x²+8x+3
y=16x+4x²-x⁴
y=x²(x-2)²
a³y=x⁴
9a³y=x(4a-x)³
a³y=x²(2a²-x²)
a³y=x³(4a-3x)
a⁵y=x⁴(3a²-2x²)
