Describe the differences between expendable and permanent molds.

Explanation of Solution

Expendable molds	Permanent molds
1. These comprise ceramics, plaster, sand, and blended with binders to enhance characteristics.	1. These comprise metals which sustains their strength at higher temperatures.
2. Once the casting is hardened, it is time to break the mold so as to get rid of the casting. That’s why we call it expendable.	2. These molds are utilized time and again. That’s why it is called permanent molds.

given below: A rectangular wing with wing twist yields the spanwise circulation distribution kbV1 roy) = kbv. (2) where k is a constant, b is the span length and V. is the free-stream velocity. The wing has an aspect ratio of 4. For all wing sections, the lift curve slope (ag) is 2 and the zero-lift angle of attack (a=0) is 0. a. Derive expressions for the downwash (w) and induced angle of attack a distributions along the span. b. Derive an expression for the induced drag coefficient. c. Calculate the span efficiency factor. d. Calculate the value of k if the wing has a washout and the difference between the geometric angles of attack of the root (y = 0) and the tip (y = tb/2) is: a(y = 0) a(y = ±b/2) = /18 Hint: Use the coordinate transformation y = cos (0)
