Answer:

Row D ; 280 Nm

Explanation:

Workdone is the product of the force applied and the distance moved. This means :

Workdone = Force * distance

For each of rows A to D:

Row A :

Workdone = 20 N * 20m = 400 Nm

Row B :

Workdone = 40 N * 10m = 400 Nm

Row C :

Workdone = 50 N * 6m = 300 Nm

Row D :

Workdone = 70 N *4m = 280 Nm

From the result obtained above, the smallest amount of workdone on the trolley is given in Row D ; which is 280Nm

One of the most important properties of materials in many applications is strength. Two of the qualitative measures of the stren

katrin2010 [14]

To solve this exercise it is necessary to take into account the concepts related to Tensile Strength and Shear Strenght.

In Materials Mechanics, generally the bodies under certain loads are subject to both Tensile and shear strenghts.

By definition we know that the tensile strength is defined as

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

Where,

$\sigma =$ Tensile strength

F = Tensile Force

A = Cross-sectional Area

In the other hand we have that the shear strength is defined as

$\sigma_y = \frac{F_y}{A}$

where,

$\sigma_y =$ Shear strength

$F_y =$ Shear Force

$A_0 =$ Parallel Area

PART A) Replacing with our values in the equation of tensile strenght, then

$311*10^6 = \frac{F}{(15*10^{-6})(30*10^{-2})}$

Resolving for F,

$F= 1399.5N$

PART B) We need here to apply the shear strength equation, then

$\sigma_y = \frac{F_y}{A}$

$210*10^6 = \frac{F_y}{15*10^{-6}30*10^{-2}}$

$F_y = 945N$

In such a way that the material is more resistant to tensile strength than shear force.

Which of these processes are chemical reactions

White raven [17]

Explanation:

In chemical reactions, chemical changes occur.
Atoms are simply rearranged and new bonds are formed.
Chemical reactions are driven by a need for atoms to attain stability in their structure.
In all chemical reactions, a reactant or reactants gives new product i.e new substances are formed.
Most these reactions are not easily reversible.
They are usually accompanied by the release of energy.
