You may use your textbook and/or work with your classmates on these problems, but the work you submit for grading MUST be your own. Exams are due no later than 5:00 pm on Tuesday, December 42 I. The box shown has dimensions: a bc 6 ft. The temperature at any point within the box is given by the formula: T T(x, y, z) x2 +4yz. Compute the average temperature within the box by evaluating a triple integral in Cartesian coordinates. The center of pressure of a vertical sail on a sailboat is the point (tpyp) at which the total aerodynamic force on the sail may be assumed to act. If the sail is represented by a plane region D, then the center of pressure is given by the formula 2. Parts Of The Mainsail Baten Topping Litt Reefing Use this formula to find the center of pressure on a sail represented by the triangular region D in the xy-plane with vertices (units are meters): Cunningham
