Answer:
a) P = 44850 N
b) 
Explanation:
Given:
Cross-section area of the specimen, A = 130 mm² = 0.00013 m²
stress, σ = 345 MPa = 345 × 10⁶ Pa
Modulus of elasticity, E = 103 GPa = 103 × 10⁹ Pa
Initial length, L = 76 mm = 0.076 m
a) The stress is given as:
on substituting the values, we get
or
Load, P = 44850 N
Hence<u> the maximum load that can be applied is 44850 N = 44.85 KN</u>
b)The deformation (
) due to an axial load is given as:
on substituting the values, we get
or
Answer:
On 2 October 1836, the Beagle entered the English port of Falmouth after a voyage which had lasted for four years, nine months and five days.
Answer: 8.8e-3 rad/s², 0.0 m/s²
Explanation:
R = 35 / 2 = 17.5 m
a = 2.3 m/s / 15 s = 0.1533333... m/s²
α = a/R = 0.1533333/17.5 = 0.0087619... ≈ 8.8e-3 rad/s² ◄(a)
at maximum speed, no more acceleration in either tangential or angular
α = a = 0.0 rad/s² or m/s² ◄(b)
Answer:
35
Explanation:
total magnification = eyepiece lens x objective lens
TM = 10X x 25X
TM = 250X
