The following equation can be used to model the deflection of a sailboat mast subject to a wind force: di (2-3) where f = wind force, E = modulus of elasticity, L = mast length, and I = moment of inertia. Note that the second order differential equation can be decoupled into the following two first order differential equations: =w de EU (2-2) dz Write a program that uses the fourth-order Runge-Kutta method to calculate the deflection distribution along the mast and plot it against z if y = 0 and dy/dz= 0 at z = 0. Use parameter values of f = 60, L = 30, E = 1.25 x 10®, and I = 0.05 for your computation For the first three problems submit: a copy of any script and function used in the problem (m), a copy of the command line input/output associated with the problem, any plots generated, and a brief summary (one or two sentences).

Signal sets company contracts to deliver one hundred 52-inch plasma high-definition television sets to a new retail customer, tuner tv store, on may 1, with payment to be made on delivery. signal tenders delivery in its own truck. tuner's manager notices that some of the cartons have scrape marks. tuner's owner phones signal's office and asks whether the sets might have been damaged as they were being loaded. signal assures tuner that the sets are in perfect condition. tuner tenders signal a check, which signal refuses, claiming that the first delivery to new customers is always for cash. tuner promises to pay the cash within two days. signal leaves the sets with tuner, which stores them in its warehouse pending its "grand opening sale" on may 15. two days later, tuner's stocker opens some of the cartons and discovers that a number of the sets are damaged beyond ordinary repair. signal claims tuner has accepted the sets and is in breach by not paying on delivery. will signal succeed on these claims? explain.

Technician a says that if a valve is open when a piston rises to the very top of a cylinder, the piston may actually strike the valve head and cause serious engine damage. technician b says if the camshaft is located in the engine block, then the engine is called an overhead valve engine, ohv engine, or an in-block camshaft. who is right? a. b only b. both a and b c. a only d. neither a nor b

Write a full class definition for a class named player , and containing the following members: a data member name of type string .a data member score of type int .a member function called setname that accepts a parameter and assigns it to name . the function returns no value.a member function called setscore that accepts a parameter and assigns it to score . the function returns no value.a member function called getname that accepts no parameters and returns the value of name .a member function called getscore that accepts no parameters and returns the value of score .this is what i have, aparently this is wrong: class player{private: string name; int score; public: void player: : setname (string n){name =n; }void player: : setscore (int s){score = s; }string player: : getname (){return name; }int player: : getscore (){return score; }};
