Complete Question

Suppose in the previous example (from Machining 1 lecture) that cutting force and thrust force are measured during an orthogonal cutting operation: Fc = 1559 N and Ft = 1271 N. The chip thickness before the cut =0.5mm and the width of the orthogonal cutting operation is 3.0mm . Rake angle is equal to 10 and shear plane angle is 25.4. Based on these data, determine the shear strength of the work material.

The shear strength of the work material is $\sigma = 245.09 N/mm^2$

Explanation:

From the question we are told that the

The the cutting force is F_c = 1559N

The thrust force is $F_t = 1271\ N$

The width of the octagonal cutting operation is $w = 3.0\ mm$

The thickness is t = 0.5mm

The shear plane angle is $\theta = 25.4^o$

The shear strength of the work materiel is mathematically represented as

$\sigma = \frac{F_s}{A}$

Where F_s is the shear force which is mathematically evaluated as

$F_s = F_c cos\ \theta -F_t sin\ \theta$

Substituting values we have

F_s = 1559 cos (25.4) - 1271sin(25.4)

= 857.841N

While A is the area which is mathematically evaluated as

$A = \frac{t* w}{sin \theta }$

Substituting values

$A = \frac{0.5 *3}{sin (25.4)}$

= 3.50

Substituting this into the equation for shear strength

$\sigma = \frac{857.8}{3.5}$

$\sigma = 245.09 N/mm^2$

Answer from: Quest

this is an example of "committed" time.

committed time, as contracted time, takes need over essential and available time since it is seen as profitable work. it alludes to the time allotted to keep up a home and family. at the point when a man is commuting using committed time this individual may feel that the drive is an obligation to family, for example, strolling youngsters to class or driving a mate to work. contracted and committed time clients may feel that their commute could really compare to the commute of important or leisure time clients on the grounds that their commute is profitable work. in this manner, they might be more disposed to pick a mechanized method of movement.
