Beam Deflection
hdr.jpg" />
hi please help me with my assignement.
this beam made of steel with moduus youg of 300 gpa, cross sectional area A1 =10.10^-6 m2
A2 = 20. 10^-6 m2.
length L1 = 2m
Length L2 =1,8 m.
at he level that is very rigid ring mounted to apply the load F=8 KN.
questions :
1.calculate reaction pedestal points A and B
2. stresses that ocur in cross section A1 and A2
3. the displacement Point C.

differential equation: given $f(x)$, show that $f(x)$, $f'(x)$, and $f''(x)$ are continuous for all $x$
Let
f1(x) = 1 + x^3 for x ≤ 0 ,1 for x ≥ 0
f2(x)= 1 for x ≤ 0, 1 + x^3 for x ≥ 0
f3(x)= 3 + x^3 for all x.
show that
a) f, f' , f", are continous for all x for each f1, f2, f3.
At what angle with the direction of motion of the ship must the gun be pointed in order to hit the target?
paano po sagutan to?
A ship is traveling at a speed of 20 knots. (A knot is a nautical mile per hour, a nautical mile being approximately 1.1516 statute mile of 5280 feet each.) When directly opposite a target it fires a gun whose projectile has a velocity of 2000 feet a second. At what angle with the direction of motion of the ship must the gun be pointed in order to hit the target?
