Answer 1

Question

Chapter 2, Problem 1RQ

To determine

The ranges of θ and ϕ are not suitable for the equation (2.17) from the given list.

Expert Solution & Answer

Explanation of Solution

Calculation:

In spherical coordinates system, the variables θ and ϕ range as follows:

0≤θ≤π (or) 0≤θ≤2π

0≤ϕ≤π (or) 0≤ϕ≤2π

From the given options (b) and (f) have a range of θ∈[0,2π] and ϕ∈[0,2π] and the remaining options have θ∈[0,π] and ϕ∈[0,2π] or θ∈[0,2π] and ϕ∈[0,π] , hence the option (b) and (f) are incorrect range.

Thus, the correct options are (b) and (f).

Q Derive (continuity equation)? I want to derive clear mathematics.

motor supplies 200 kW at 6 Hz to flange A of the shaft shown in Figure. Gear B transfers 125 W of power to operating machinery in the factory, and the remaining power in the shaft is mansferred by gear D. Shafts (1) and (2) are solid aluminum (G = 28 GPa) shafts that have the same diameter and an allowable shear stress of t= 40 MPa. Shaft (3) is a solid steel (G = 80 GPa) shaft with an allowable shear stress of t = 55 MPa. Determine: a) the minimum permissible diameter for aluminum shafts (1) and (2) b) the minimum permissible diameter for steel shaft (3). c) the rotation angle of gear D with respect to flange A if the shafts have the minimum permissible diameters as determined in (a) and (b).
