Answer:
the maximum height h to which the the water steam could rise is 40.65m
Explanation:
Given;
= 20m,
= 2atm ≈ 20265 N/m
Density of water ρ = 1000 kg/
Note: we take point 1 at the free surface of the water in the tank and point 2 at the top of the water trajectory. we also take reference level at the bottom of the tank.
fluid velocity at the free surface of tank is very low (
≅ 0) and at the top of the water trajectory 
= 0
Step 1: Applying Bernoulli equation between poin 1 and point 2
/ρg + 
/2g + = 
/ρg + 
/2g + 
/ρg + = 
/ρg +
= ( - )/ρg +
Substituting values into we have,
=

Answer: Fracture will not occur since Kc (32.2 MPa√m) ∠ KIc (35 MPa√m).
Explanation:
in this question we are asked to determine if an aircraft will fracture for a given fracture toughness.
let us begin,
from the question we have that;
stress = 325 MPa
fracture toughness (KIc) = 35 MPa√m
the max internal crack length = 1.0 m
using the formula;
Y = KIc/σ√(πα) ---------------(1)
solving for Y we have;
Y = 35 (MPa√m) / 250 (MPa) √(π × 2×10⁻3/2m)
Y = 2.50
so to calculate the fracture roughness;
Kc = Y × σ√(πα) = 2.5 × 3.25√(π × 1×10⁻³/2) = 32.2 MPa√m
Kc = 32.2 MPa√m
From our results we can say that fracture will not occur since Kc (32.2 MPa√m) is less than KIc (35 MPa√m) of the material.

Answer: The NRA uses the general term “trigger control” to describe the act of moving the trigger and firing the gun without disturbing aim. ... The best method of controlling a trigger, for all levels of shooters, is to move the trigger straight to the rear, firing the gun without disturbing aim.
