For a bronze alloy, the stress at which plastic deformation begins is 294 MPa and the modulus of elasticity is 121 GPa. (a) What

is the maximum load that can be applied to a specimen having a cross-sectional area of 327 mm2 without plastic deformation? (b) If the original specimen length is 129 mm, what is the maximum length to which it may be stretched without causing plastic deformation?

Answer:

a) load in Newton is 96,138 b) 129.314mm

Explanation:

Stress = force/ area (cross sectional area of the bronze)

Force(load) = 294*10^6*327*10^-6 = 96138N

b) modulus e = stress/ strain

Strain = stress/ e = (294*10^6)/ (121*10^ 9) = 2.34* 10^ -3

Strain = change in length/ original length = DL/ 129

Change in length DL = 129 * 2.34*10^ -3 = 0.31347

Maximum length = change in length + original length = 129.314mm

Please help me with physics homework! Provide explanation.

The direction of friction force is always the opposite of the direction of the movement.

In this problem, we have an applied force of 20N and this creates a movement. Then, the friction comes in and applies a force of 2.4N.

Because they are in different directions, we need to subtract them:
20 - 2.4 = x \\  \\ x = 17.6
We don't know the direction because there is no picture (at least I can't see ☺️). But the movement will be to the direction of the 20N.

A drill has a density of 11.342 g/cm3. Its mass is 1500 g. What is the volume of the drill? Round to TWO decimal places.
Andrews [41]

Explanation:

11.342=1500/ volume

volume=1500/11.342

volume=132.25cm³
