5. The following formula can be used to describe the dimensions of a loading ramp: h sin(0) where e is the incline angle of the ramp, h is the height of the ramp, and I is the length of the ramp. Write a program that calculates the needed length of a ramp given a desired incline and height. For example, given an incline of 9.5 degrees and a height of 0.5 m, a ramp needs to be 3.03 m in length. The program should prompt the user for the needed values and calculate and report the required length. The program should make use of the math library for the sin() function, and should use the macro M_PI for the value of a to convert degrees to radians (radians = degrees x ). %3D 180

(Mechanics) The deflection at any point along the centerline of a cantilevered beam, such as the one used for a balcony (see Figure 5.15), when a load is distributed evenly along the beam is given by this formula: d=wx224EI(x2+6l24lx) d is the deflection at location x (ft). xisthedistancefromthesecuredend( ft).wistheweightplacedattheendofthebeam( lbs/ft).listhebeamlength( ft). Eisthemodulesofelasticity( lbs/f t 2 ).Iisthesecondmomentofinertia( f t 4 ). For the beam shown in Figure 5.15, the second moment of inertia is determined as follows: l=bh312 b is the beam’s base. h is the beam’s height. Using these formulas, write, compile, and run a C++ program that determines and displays a table of the deflection for a cantilevered pine beam at half-foot increments along its length, using the following data: w=200lbs/ftl=3ftE=187.2106lb/ft2b=.2fth=.3ft

PROBLEM: Write a program that computes for the Electric Field and Electric Potential at a given point in a spherical conductor with a radius (r) and a charge Q, depending upon the following cases: Calculate the electric field and electric potential at: d < r d > r d = r SPECIFICATIONS: - The program will depend on the input parameters to determine which case to use in computing for the electric field and electric potential at different points: Point is inside the conductor (d < r) Point is outside the conductor (d > r) Point is on the surface of the conductor (d = r) - The user will input the charge Q, the radius of the conductor (r) and the distance of the point from the center (d) - The constant k = 9x10^9 = 9000000000 - The program will provide an output for the electric field (V/m) and for the electric potential (V) - You may only use the codes that we studied in our lectures. - All lines of codes should have a comment/pseudocode. - Save your cpp file as…
Write python code:
Matlab A rocket is launched vertically and at t-0, the rocket's engine shuts down. At that time, the rocket has reached an altitude of ho- 500 m and is rising at a velocity of to 125 m/s. Gravity then takes over. The height of the rocket as a function of time is: h(t)-ho+vot-gt², t20 where g -9.81 m/s². The time t-0 marks the time the engine shuts off. After this time, the rocket continues to rise and reaches a maximum height of Amax meters at time t = tmax. Then, it begins to drop and reaches the ground at time t = tg. a. Create a vector for times from 0 to 30 seconds using an increment of 2 s. b. Use a for loop to compute h(t) for the time vector created in Part (a). e. Create a plot of the height versus time for the vectors defined in Part (a) and (b). Mark the and y axes of the plot using appropriate labels. d. Noting that the rocket reaches a maximum height, max, when the height function, h(t), attains a maxima, compute the time at which this occurs, max, and the maximum height,…

C++ Program
The formula for a line is normally given as y=mx+b. Using C++ write a method Line() that expects three float parameters: a slope m, a y-intercept b and an x-coordinate x. The method computes the y-coordinate associated with the line specified by m and b at x-coordinate.
(Statics) A beam’s second moment of inertia, also known as its area moment of inertia, is used to determine its resistance to bending and deflection. For a rectangular beam (see Figure 6.6), the second moment of inertia is given by this formula: Ibh3/12 I is the second moment of inertia (m4). b is the base (m). h is the height (m). a. Using this formula, write a function called beamMoment() that accepts two double- precision numbers as parameters (one for the base and one for the height), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 4a in a working program. Make sure your function is called from main(). Test the function by passing various data to it.
(Statics) An annulus is a cylindrical rod with a hollow center, as shown in Figure 6.7. Its second moment of inertia is given by this formula: I4(r24r14) I is the second moment of inertia (m4). r2 is the outer radius (m). r1 is the inner radius (m). a. Using this formula, write a function called annulusMoment ( ) that accepts two double-precision numbers as parameters (one for the outer radius and one for the inner radius), calculates the corresponding second moment of inertia, and displays the result. b. Include the function written in Exercise 5a in a working program. Make sure your function is called from main(). Test the function by passing various data to it.
(Electrical eng.) a. The voltage gain of an amplifier is given by this formula: voltagegain=[275 23 2 +0.5 f 2 ]n f is the frequency in Hz. n is the number of stages in the amplifier. Using this formula, write, compile, and run a C++ program to determine the value of the voltage gain for a four-stage amplifier operating at a frequency of 120 Hz. Your program should produce the following display: At a frequency of xxxxx hertz, the voltage gain is yyyyy Your program should replace xxxxx with the frequency and yyyyy with the voltage gain. b. Manually check the value your program produces. After verifying that your program is working correctly, modify it to determine the voltage gain of a 12-stage amplifier operating at a frequency of 9500 Hz.
