- (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=.3ftCodingPROBLEM: 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…

These equations are usually written in the following form:ax2 + bx + c = 0The Quadratic Formula x = ( -b ± √( b^2 - 4ac ) ) / ( 2a ) Where a, b, and c are constants with a ≠ 0. (If a = 0, the equation is a linear equation.)The discriminant is the part of the formula in the square root. If the value of the discriminant is zero then the equation has a single real root. If the value of thediscriminant is positive then the equation has two real roots. If the value of thediscriminant is negative, then the equation has two complex roots.Write a program that finds the roots of the quadratic equation using the Quadratic Formula. Write a function named discriminant in the file, Disc.py, to calculate and return the discriminant of the formula. Let the main function call the discriminant function and then calculate the solution(s) of the equation. Do not calculate the solutions in the discriminant…
- Python Programming Part: Carbon-14 is constantly produced in Earth's upper atmosphere due to interaction between cosmic rays and nitrogen, and is found in all plants and animals. After a plant or animal died, its amount of carbon-14 decreases by about 0.012% per year. Write a python code to determine the half-life of carbon-14, that is, the number of years required for 1 gram of carbon-14 to decay to less than 1/2 gram. Example Output: Carbon-14 has a half-life of years. >>>A Moment that arise from a load is calculated by means of the applied load multiplied by the distance between the applied load and support. For instance: In the figure below, a load of 10 kN is applied at 4m away from point A. In this case, the moment at the point A will be 10 kN X 4 m = 40 kN.m 10 KN 4 m A 5 m Write a program in C or Python that calculates the moment at the support (point A) depending on the amount of the load applied and the distance of the load off the point A, which will be entered by user. (Other programming languages will not be accepted). Note: the load can be applied within the length of the beam. Examples: Please enter the distance of the load away from point A (0 - 5m): 4 Please enter amount of load: 10 The moment applied to point A is 40 kN.m Process finished with exit code 0 Please enter the distance of the load away from point A (0 - 5m): 6 Please enter amount of load: 5 the distance should be between 0-5 m Process finished with exit code 0 Please enter…Write python code:
