Answer:
stress = 50MPa
Explanation:
given data:
Length of strain guage is 5mm
displacement
stress due to displacement in structural steel can be determined by using following relation


where E is young's modulus of elasticity
E for steel is 200 GPa

stress = 50MPa
Answer:
Technician A and Technician B both are correct.
Explanation:
Technician A accurately notes that perhaps the forms of combustion process most widely used are hemispherical and cross.
Technician B also correctly notes that in several cylinder heads, cooling system and greases gaps and pathways are found.
