Answer:
C. Decrease your consumption of beef.
Explanation:
The production of beef needs lots of land, which leads to trees being cut down, releasing carbon dioxide. Also, the ruminant animals used to produce beef end up farting a lot from their diets, and these farts are of high metane, which leads to greenhouse gases being emitted in the athmosphere.
Common plant proteins, otherwise, produce way less of these gases.
So the correct answer is:
C. Decrease your consumption of beef.
Answer:
The correct option is: (b) Shearing stress
Explanation:
The shear stress is described as the force that results in the deformation of an object or substance. It originates from the vector of the force component that is parallel to area of cross section of the object or substance.
The paired shear forces that produces shear stress, act equally on the opposite sides of the given object.
<u>In the given example, the stress produced when using scissors for cutting, is known as the shear stress.</u>
Answer:
See explanation below
Explanation:
Hypo-eutectoid steel has less than 0,8% of C in its composition.
It is composed by pearlite and α-ferrite, whereas Hyper-eutectoid steel has between 0.8% and 2% of C, composed by pearlite and cementite.
Ferrite has a higher tensile strength than cementite but cementite is harder.
Considering that hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains whereas hypereutectoid steel contains a higher amount of cementite, the following properties are obtainable:
Hypo-eutectoid steel has higher yield strength than Hyper-eutectoid steel
Hypo-eutectoid steel is more ductile than Hyper-eutectoid steel
Hyper-eutectoid steel is harder than Hyper-eutectoid steel
Hypo-eutectoid steel has more tensile strength than Hyper-eutectoid steel.
When making a knife or axe blade, I would choose Hyper-eutectoid steel alloy because
1. It is harder
2. It has low cost
3. It is lighter
When making a die to press powders or stamp a softer metals, I will choose hypo-eutectoid steel alloy because
1. It is ductile
2. It has high tensile strength
3. It is durable
Answer:
1. Cast iron or aluminum
2. aluminum (first blank) iron(second blank)
3. aluminum
4. dry sleeve
5. Wet sleeve
6. matching operation that cuts a series of holes through the block for crankshaft bearing
