1. dia a\t2.8064

dia b\t2.8075

Explanation:

Step1: Determine maximum diameter of DIA A

From Figure 7 - 19, the tolerance for DIA A is $_{+0.0014}^{+0.0000}$. The basic dimension of DIA A is 2.8064 in. The maximum diameter is the basic dimension plus the upper - tolerance value. So, the maximum diameter of DIA A is $2.8064 + 0.0014=2.8078$ in.

Step2: Determine minimum diameter of DIA A

The minimum diameter is the basic dimension plus the lower - tolerance value. So, the minimum diameter of DIA A is $2.8064+0 = 2.8064$ in.

Step3: Determine maximum diameter of DIA B

From Figure 7 - 19, the tolerance for DIA B is $_{+0.0000}^{-0.0014}$. The basic dimension of DIA B is 2.8075 in. The maximum diameter is the basic dimension plus the upper - tolerance value. So, the maximum diameter of DIA B is $2.8075+0 = 2.8075$ in.

Step4: Determine minimum diameter of DIA B

The minimum diameter is the basic dimension plus the lower - tolerance value. So, the minimum diameter of DIA B is $2.8075-0.0014 = 2.8061$ in.

Step5: Calculate maximum clearance

Maximum clearance occurs when the hole (DIA A) is at its maximum size and the shaft (DIA B) is at its minimum size. So, maximum clearance $=2.8078 - 2.8061=0.0017$ in.

Step6: Calculate minimum clearance

Minimum clearance occurs when the hole (DIA A) is at its minimum size and the shaft (DIA B) is at its maximum size. So, minimum clearance $=2.8064 - 2.8075=- 0.0011$ in.

Answer:

	Basic Dimension (in.)	Maximum Diameter (in.)	Minimum Diameter (in.)	Maximum Clearance (in.)	Minimum Clearance (in.)
DIA B	2.8075	2.8075	2.8061	0.0017	- 0.0011
