Answer:
1. Slope = 53.3 x 10⁻⁶
2. Deflection = -0.00016m
Explanation:
given:
let L = 4 m (span of cantilever beam)
let w = 300 N/m (distributed load)
let EI =60 MNm² (flexural stiffness)
dy w * L³ 300 x 4³
1. slope = ------- = --------- = ------------------- = 53.3 x 10⁻⁶
dx 6EI 6 x 60x10⁶
wL⁴ 300 x 4⁴
2. Deflection = y = - ----------- = - ------------------ = -0.00016m
8EI 8 x 60x10⁶
therefore the deflection is 0.16mm downwards.
Answer: 12.4 feet
Explanation:
If there is a smooth transition and there is no change in slopes, energy considerations can be used
The cube has a kinetic energy of
ke = mv^2/2 = 10 lbm * 20^2ft^2/s^2 / 2 = 2000 lbm-ft^2 / s^2
At the highest point when there is a gain in potential energy
pe = mgh = 10 lbm * 32.2 ft/s^2 * h ft = 322 lbm ft^2/s^2
If there is no loss in energies,
pe = ke
322h lbm ft^2/s^2 = 2000 lbm ft^2/s^2
h = 2000 /322 = 6.211 (ft)
= h / sin(30) = 12.4 ft

Answer is INHERITANCE.
Explanation:
In object oriented programming:
An object is a self-contained component that contains properties and methods needed to make a certain type of data useful.
A class is a blueprint or template used to build a specific type of object. Every object is built from a class.
Inheritance is a way to express relationship between classes. Inheritance enables new objects (subclasses) to take on the properties of existing objects (superclasses).
A class that is used as a basis for inheritance is called a superclass or base class or parent class.
A class that inherits from a superclass is called subclass or derived class or child class.
The ability of a subclass to override a method allows a class to INHERIT from a superclass whose behavior is "close enough" and then to modify behavior as needed.
Therefore, the characteristic of object oriented programming that allows the method in subclass that overrides the same method in the superclass to be correctly called from an instance of that superclass is called INHERITANCE.
Answer: C. There is no relationship
Explanation:
At the various temperatures, the flow rates do not seem to show any relation as similar temperatures can yield different flow rates.
The flow rates neither appear to generally increase nor decrease as a result of a decrease or an increase in temperature which means that there is a lack of a positive, negative and curvilinear relationship.
There is simply no relationship.
