c.
d. X number of teeth

Answer 1

$\huge{\boxed{\mathtt{\red{ANSWER}}}}$

a) 1

Answer 2

Correct Question: The diametral pitch times the circular pitch is equal to

a. 1               b. 1/2               c. $\pi$               d. 0

Answer:

The diametral pitch times the circular pitch is $\pi$.

Step-by-step explanation:

Diametral pitch, $p_d$ : The number of teeth per the diameter of the pitch circle is known as diametral pitch. Symbolically,

$p_d=\frac{T}{D}$

Circular pitch, $p_c$ : The distance between the corresponding points of the adjacent teeth measured on the pitch circle is called circular pitch. Symbolically,

$p_c=\frac{\pi D}{T}$

According to the question,

The diametral pitch times the circular pitch is

⇒ $\frac{T}{D}$ × $\frac{\pi D}{T}$

⇒ $\pi$

Therefore, the diametral pitch times the circular pitch is $\pi$.
