A 65-tooth spur gear is in mesh with a 32-tooth pinion. For a diametral pitch equal to 7 and pressure angle equal to 20 degrees.
alex41 [277]

Answer:

0.4488 mm

Explanation:

Number of teeth in spur gear = 65

Number of teeth in pinion = 32

Diametral pitch = 7 = P

pressure angle = ∅ = 20°

Circular pitch of measured on the pitch circle is defined as the distance between two corresponding points.

Circular pitch

p=\frac{\pi}{P}\\\Rightarrow p=\frac{\pi}{7}\\\Rightarrow p=0.4488\ mm

So, the circular pitch is 0.4488 mm

What is a truss? What separates a truss from a frame and other forms of rigid bodies?
tangare [24]

Answer:

The application of force is the main difference between truss and frame.

Explanation:

<u>Truss: </u>

Truss is a collection of beams,which use to handle the tensile and   compression loads . That collection of beams creates rigid structure.

The load on the truss will be acting always at the  at the hinge. Truss is     widely used in the construction areas.                

<u>Frame:</u>

       Like truss, it is also a combination of beams and used to handle the loads. The main difference between truss and frame is the application of load. In the frame load can apply at the any point of the member of frame along  with hinge.

Truss are connected by pin joint and can not transfer moment ,on the other hand frames are connected by rigid joint like welding so frame can transfer moment.

Truss and frame both forms a rigid structure and is used in the construction areas.

A flat plate has a length L = 1 m and experiences air flow parallel to the surface. Transition from laminar to turbulent flow oc
tresset_1 [31]

Answer:

velocity is 15.083 m/s

Explanation:

given data

length L = 1 m

Laminar to turbulent flow

xc = 0.5 m

Reynolds number Rex, c = 5 × 10^{5}  

solution

we take here for 350 K

\mu  = 1.81 × 10^{-5}  

and here   Reynolds number Rex, is express as

Rex = \frac{\sigma \times v \times x}{\mu }   ................1

put here value at x = 0.5

5 × 10^{5}   = \frac{1.2\times v \times 0.5}{1.81\times 10^{-5} }  

solve it we get

v = 15.083 m/s

so velocity is 15.083 m/s
