Answer:

Kitchen sinks can be clogged for a few reasons, food hair, and other things. Overtime, buildup of these things lead to clogging.

A few methods to fix clogging are, baking soda mixture, plunging, and boiling water.

The first method, baking soda mixture, what you do is you pour a cup of baking soda and vinegar down the drain, and place a rubber stopper to cover the drain opening. Wait 10 or more minutes, and take out the stopper, and run hot tap water until it's unclogged.

The second method is plunging. Make sure the sink has enough water to submerge the plunger, and start plunging. While you are plunging, maintain a good seal to get the best results. This usually works, but sometimes it doesn't.

The last method is boiling water. Pour boiling water into the drain, then after a while, the clogged drain should unclog, if it doesn't repeat the process until necessary.

When calculating a resolved shear stress within a single unit cell, the angle between the applied stress direction and the slip

givi [52]

Answer: 35.3 °

Explanation:

Body-centered cubic lattice (bcc or cubic-I), just like all lattices, has lattice points at the eight corners of the unit cell with an additional points at the center of the cell. It has unit cell vectors a = b = c and interaxial angles α=β=γ=90°.

The simplest crystal structures are those that have present only a single atom at each lattice point.

body-centered cubic unit cell has atoms at each of the eight corners of a cube (like the cubic unit cell) plus one atom in the center of the cube. Each of the corner atoms is the corner of another cube so the corner atoms are shared between eight unit cells. It is said to have a coordination number of 8. The bcc unit cell consists of a net total of two atoms; one in the center and eight eighths from corners atoms

With the use of BCC unit cell, if a applied stress is in [110] direction, but slip applies in [111] direction, the angle between applied direction and slip direction is given as:

[1 1 0] [1 1 1]

λ = Cos^-1 ( 1×1 + 1×1 + 0×1 ÷ (1^2 + 1^2 +0^2) (1^2 + 1^2+ 1^2))

Cos^-1 2/ sqrt 6

= 35.386°

Alyssa works for an engineering firm that has been hired to design and supervise the construction of a highway bridge over a maj

Colt1911 [192]

Answer:

I'm going to make a list of everything you need to consider for the supervision and design of the bridge.

1. the materials with which you are going to build it.

2. the length of the bridge.

3. The dynamic and static load to which the bridge will be subjected.

4. How corrosive is the environment where it will be built.

5.wind forces

6. The force due to possible earthquakes.

7. If it is going to be built in an environment where snow falls.

8. The bridge is unique,so the shape has a geometry that resists loads?.

9. bridge costs.

10. Personal and necessary machines.

11. how much the river grows

If the coefficient of static friction between the block and the platform is μs = 0.4, determine the maximum speed which the bloc

MrRa [10]

Question:

A disc of radius 6m is rotating about its fixed centre with a constant angular velocity 3rad/s ( in the horizontal plane). A block is also rotating with the disc without slipping. If coefficient of friction between the block and disc is 0.4, determine the maximum speed which the block can attain before it begins to slip. Assume the angular motion of the disk is slowly increasing.

Answer:

Maximum Radius = 0.44m

Given

r = Radius = 6m

w = Angular Velocity = 3rad/s

μ = coefficient of friction between the objects = 0.4

There are four forces acting on the objects

1. Centripetal Forces

2. Friction

3. Blocks weight

4. Normal force on the block

The centripetal force acts inward toward the disk center.

The friction hinders the block's motion.

The block's weight acts on the disk

The normal force of the disk acting on the block.

The block's weight is equal to the normal force on the block because the block sits on the desk surface.

Centripetal force, Fc = mw²r

Friction,Fr = μN where N = Normal force = mg

Friction = μmg

The maximum distance rmax that we could place the block would be when Ff < Fc

We assume they are equal to solve for r

Ff = Fc

μmg = mw²r ---- divide through by m

μg = w²r ----- make r the subject of formula

r = μg/w² where g = 9.8m/s²

Plugging in the values

r = 0.4 * 9.8/3²

r = 0.435555555555555

r = 0.44m ----- Approximated
