Answer:
88.2N
Explanation:
Coefficient of static friction = force (P)/(mass × acceleration due to gravity)
Force (P) = coefficient of static friction × mass × acceleration due to gravity = 0.3 × 30 × 9.8 = 88.2N
The modulus of elasticity is 44.4GPa
E<u>xplanation:</u>
Given
original length L1=10cm
New length L2=10.036 cm
Force F=16000N

Stress of the bar σ=Force/Area

Change in length ΔL=L2-L1=10.036-10=0.036 cm
Strain is obtained by dividing the change in length by original length
Strain ε=ΔL/L1
=0.036/10=0.0036
Modulus of elasticity=stress/strain
=σ/ε
Pa
