An aluminium bar 600mm long with diameter 40mm has a hole drilled in the centre of the bar. The hole is 30mm in diameter and is

KengaRu [80]

Answer:

The total contraction of the bar is 1.228 mm

Explanation:

The parameters given are;

Length of aluminium bar = 600 mm

Diameter of aluminium bar = 40 mm

Diameter of hole in aluminium bar = 30 mm

Length of hole = 100 mm

Modulus of elasticity of aluminium = 85 GN/m²

Applied compressive load = 180 kN

$\delta = \dfrac{P \times L}{A \times E}$

Where:

δ = Total contraction of the bar

A₁ for the hole section = $\frac{1}{4 }\times (40^{2}-30^{2}) \times \pi = 549.78 \, mm^2$

A₂ for the solid section = $\frac{1}{4 }\times 40^{2} \times \pi = 1256.64 \, mm^2$

L₁ = 100 mm

L₂ = 600 - 100 = 500 mm

$\delta = \dfrac{P}{E} \times\left ( \dfrac{L_1}{A _1} + \dfrac{L_2}{A _2} \right ) = \dfrac{180000}{85000} \times\left ( \dfrac{100}{549.78} + \dfrac{500}{1256.64} \right ) = 1.228 \ mm$

The total contraction of the bar = 1.228 mm.

A cylindrical specimen of a brass alloy having a length of 60 mm (2.36 in.) must elongate only 10.8 mm (0.425 in.) when a tensil

Gemiola [76]

The radius of the specimen is 60 mm

Explanation:

Given-

Length, L = 60 mm

Elongated length, l = 10.8 mm

Load, F = 50,000 N

radius, r = ?

We are supposed to calculate the radius of a cylindrical brass specimen in order to produce an elongation of 10.8 mm when a load of 50,000 N is applied. It is necessary to compute the strain corresponding to this

elongation using Equation:

ε = Δl / l₀

ε = 10.8 / 60

ε = 0.18

We know,

σ = F / A

Where A = πr²

According to the stress-strain curve of brass alloy,

σ = 440 MPa

Thus,

$sigma = 50,000 / \pi (r)^2\\\\440 X 10^6 = \frac{50,000}{3.14 X (r)^2}\\\\r = 0.06m\\r = 60mm\\\\\\$

Therefore, the radius of the specimen is 60 mm

What is an isochoric process? b) Can heat be exchanged in an isochoric process? c) A 100L container holding an ideal gas at an i

oksano4ka [1.4K]

Answer:

a)A constant volume process is called isochoric process.

b)Yes

c)Work =0

Explanation:

Isochoric process:

A constant volume process is called isochoric process.

In constant volume process work done on the system or work done by the system will remain zero .Because we know that work done give as

work = PΔV

Where P is pressure and ΔV is the change in volume.

For constant volume process ΔV = 0⇒ Work =0

Yes heat transfer can be take place in isochoric process.Because we know that temperature difference leads to transfer of heat.

Given that

Initial P=10 MPa

Final pressure =15 MPa

Volume = 100 L

Here volume of gas is constant so the work work done will be zero.
