Based on this information, respond to the following:

• How can the long-run average cost (LRAC) curve be derived from the short-run average total cost (SRATC) curve?
• Describe economies of scale and diseconomies of scale.
• What are the determinants of economies of scale and diseconomies of scale, respectively?
• Using a real-world company (other than Sysco), explain the causes of economies of scale for your company.
• Explain how economies of scale help your company compete in its industry.

A general vibrating model of a vehicle is called the full car model. Such a model, that is shown in Figure below, includes the body bounce x, body roll , body pitch 0, wheels hop x1, x2, x3, and x4 and independent road excitations y1, y2, y3, and y4. A full car vibrating model has seven DOF with the following equations of motion. mx + c (* * + b ) + ( - 10) + ( + 0) + C ( + + 0) +kf (x x + b - 0) + k (x x-b - 0) +kr (x-x3-b1 + a20) + kr (x x4 + by + a0) = 0 I+b ( + b 0) bc ( * b4 0) bin (trg bi tai +hen ca+hp tay) - +bkf (x-x + b-a0) -bkf (x - x-b-a0) -bkr (x x3 by + a20) + bkr (x x4 + by + 20) - + KR (p 1 = 22 ) = 0 - W a1cf Iy ( + b 0) c ( b 0) +c, ( 3 b + a0) + 2cr ( + b + 0) -ak (x x + b-a0) - ak (x-x2-b4 - 0) +akr (x-x3-b + a20) + a2kr (x x4 + by + a0)=0 (12.254) kf Cf m kif S V2 KRf b aj mi kif X kf cf (12.252) a2 1 (12.253) m, Ix, ly KRr FIGURE 12.14.
