A certain engineering system can be represented by mass in a spring, as shown in Figure 1. If the mass is pulled downwards and then released, it oscillates on the spring. Using Newton¡¯s second law, a homogeneous second-order differential equation can be set up as below: If the mass m is 1kg and the spring¡¯s stiffness k is 100N/m, find an expression for the displacement x with respect to time t, when t=0, x(0)=0 and x`(0)=1 ...........Diagram .....

A tailor makes wool tweed sport coats and wool slacks.

1. Consider the following linear programming model: Maximize Z=5 x1 + 4x2 Subject to 3x1+4x2≤10 X1, x2≥0 and integer Demonstrate the graphical solution of this model. 3. A tailor makes wool tweed sport coats and wool slacks. He is able to get a shipment of 150 square yards of wool cloth from Scotland each month to make coats and slacks, and he has 200 hours of his own labor to make them each month. A coat requires 3 square yards of wool and 10 hours to make, and a p... click for more
