Anyone for Problem 1 and 2 please?
The small tapered bar BC has length L=0.1 m and is made of a homogeneous material with Young’s modulus E=10 GPa. The cross sectional area of the bar is slowly varying between A0=160 mm^2 (at B) and A0/2 (at C), as described by the function:
A(x)=A0/(1+(x/L))
The bar is fixed at B and a load P=8kN is applied at the free end C. Determine the total elongation, δ, of the bar. (in mm)

Anyone for Problem 1 and 2 please?
Yes, Problem 1+2 please?
Problem 1 and 2 please?
Do you have problem 1 and 2?
RORO did you get problem 1 and 2 please?
So:fx(x)=rho_1*g*A
I don't understand why f depends on x
Try typing it, not copy/paste.
rho_1 isn't allowed for L/2 to L
Have you had luck with Problem 2?
A blade is fixed to a rigid rotor of radius R spinning at ω rad/sec around the vertical z-axis (see figure). Neglect the effects of gravity.
4.
5.Calculate the peak stress in the blade: σmaxn
6.Calculate the blade elongation: δ
7.Calculate the displacement of the blade mid-section: ux(L/2)
8.Given:
9.Young's modulus, E , mass density, ρ .
· Constant cross sectional area, A
· Rotor radius R , blade length L
· Angular velocity ω
(Hint: if you work in the non-inertial frame of the rotating blade, the d'Alembert force/unit volume is ρω2r along the +x direction)

plzzzzzzzzzzzzzzzz help.
The composite bar is composed of an inner core of cross sectional area A and a sleeve of cross sectional area . The Young's modulus of the sleeve is and the modulus of the core is . Under the effects of unknown distributed loading, , the bar is observed to deform. The measured displacement field in the bar is , where is a dimensional constant and is the length of the bar. The origin of the x-axis is at the fixed support,10M . The maximum magnitude (absolute value) of stress in the core is found to be Pa.
