A cylindrical specimen of a nickel alloy having
tia_tia [17]

Answer:

L = 0.475 m = 475 mm = 18.7 inches

Explanation:

A cylindrical specimen of a nickel alloy having an elastic modulus of 207 GPa and an original diameter of 10.2 mm (0.40 in.) will experience only elastic deformation when a tensile load of 8900 N (2000 lb ) is applied. Compute the maximum length of the specimen before deformation if the maximum allowable elongation is 0.25 mm (0.010 in).

E = 207 GPa = 207*10⁹ Pa

D = 10.2 mm = 0.0102 m

P = 8900 N

ΔL = 0.25 mm = 2.5*10⁻⁴ m

L = ?

We can use the Equation of the Hooke's Law

ΔL = P*L / (A*E)    ⇒   L = ΔL*A*E / P

⇒   L = (2.5*10⁻⁴ m)*(π*(0.0102 m)²*0.25)*(207*10⁹ Pa) / (8900 N)

⇒   L = 0.475 m = 475 mm = 18.7 inches

A raft is made using a number of logs (TBD) with 25-cm diameter and 2-m-length. It is desired that a maximum 90 percent volume o
Vilka [71]

Answer:

6logs

Explanation:f

First finding the volume of the logs

V= π/4d²l

= 0.098m³

So number of logs will be

Weight of 2 boys + weight of log = buoyancy force.

So

2( 400)+ N ( Mlog x g) = density of water x volume displaced x g

2(400) = N x 0.098x 1000x 9.8 x 0.9- 0.75* 1000

N= 5.5 which is approx 6logs
