- Question 6: The volume of a box with sides of length a,b and c is V = abc . The surface area of the same box is S = 2(ab+bc+ ac). Derive an expression for the change in volume associated with changing the length a, while holding both S and length b constant. (Hint: The algebra here becomes much simpler than it might first appear through the judicious use of partial derivative relationships.)Q5One day, you are driving your car down the highway, and you notice that you are driving well over the speed limit. You apply the brakes of the carapplying a variable stopping force, until the car slows down to a rea sonable speed of 22.4 m/s (50 mph)A computer plots the force versus time for the vehicle and then measures the area under the curve. It is found that the area is - 18.950N . The total breaking time was 5.4 s. Given that the combined mass of you and your car 1sm = 1200 kg how fast were you moving before applying the breaks? What is the average force applied by the road to the car during breaking? (Note: 1Ns=1kg* m/s)

What will be the average speed in meters per second?A cube with the dimensions bXbXb with mass m lies on the flat horizontal ground. One the side shown in the figure. The thickness normal to the plane of the figure is b. The cube is subject to the earth's gravity and the friction coefficient between the cube abd the ground is mu. Express your answer in terms of the given variables. What is the minimum force required to produce sliding? What is the minumum force required to produce tipping of the cube? Assume the cube is rotating about O. Impulsive horizontal loading L is applied on the edge B such that force F(t) is applied during the very short time delta t: where L= the integral from zero to delta t of F(t)dt. What is the minimum value of the impulse for which the cube tips over and falls on side OA.A beam is supported by a roller at A and a pin at B. Determine the reactions at A and B when P = 15 kips. Neglect the weight of the beam.
