Answer:
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm
Explanation:
Hi, the ruler is in centimeters, from left to right each long line ( the ones with the number ) is a centimeter.
Since 10 millimeter equals 1 centimeter each short line is a millimeter (0.1 cm)
Knowing this, the measures of each block are.
Pink block = 1.4 cm
Green block= 1.5 cm
Blue block= 1.7 cm

Answer:
81.76 N/mm² ( MPa), 1.71233
Explanation:
Modulus of elasticity = stress / strain
stress = modulus of elastic × strain
strain = ΔL / L = 250.28 mm - 250 mm / 250 mm = 0.00112
Modulus of elasticity E = 73 GPa = 73 × 10³ MPa where 1 MPa = 1 N/mm²
E = 73 × 10³N/mm²
stress = 73 × 10³N/mm²× 0.00112 = 81.76 N/mm² ( MPa)
b) Factor of safety = maximum allowable stress / induced stress = 140 MPa / 81.76 MPa = 1.71233
Capillary action occurs When the adhesion to the walls stronger than dirt cohesive forces between a liquid molecules. the head towards Capillery action will take water in a uniform circular is limited by surface tension and, of course, gravity.
