The amount of straight pipe needed to bend a given radius. Also, the actual length of the conduit that will be bent.
1 answer:
Development length: The actual length of the bent conduit. Gain: Since a conduit bends radially rather than at an angle, the total length will not match the length required for all bends. Gain is the amount of space that is saved by a curve.
Conduit benders from Klein Tools are built to function and last longer than even the highest professional standards. To ensure a favourable experience and significantly enhance the final result of your project, it is advised that you become familiar with bending concepts, procedures, and the bender's capabilities. The benders are labelled with various alignment symbols to enable the operator make the bends required to complete any job. This aids bending while executing a ground or air bend. Arrow, teardrop, star point, and angle markings are the symbols on the Klein Tools benders. On certain bender head sides, you can see these markings.

Answer:
The coefficient of kinetic friction is 0.382.
Explanation:
Given:
Angle of inclination is, °
Mass of package is,
Initial speed of package is,
Final speed of the package at the bottom is,
Distance of travel along the incline is,
Acceleration due to gravity is,
Let the coefficient of kinetic friction be .
Now, the frictional force will be acting along the incline but in the direction opposite to the direction of motion.
So, the net acceleration acting on the package will be up the incline and is equal to:
----------------- 1
Now, using equation of motion, we have:
Solving for 'a', we get:
Now, plug in the value of 'a' in equation (1). This gives,
( Neglecting negative sign)
Plug in all the given values and solve for . This gives,
Therefore, the coefficient of kinetic friction is 0.382.
Answer:
8977.7 kg/m^3
Explanation:
Volume of water displaced = 55 cm^3 = 55 x 10^-6 m^3
Reading of balance when block is immersed in water = 4.3 N
According to the Archimedes principle, when a body is immersed n a liquid partly or wholly, then there is a loss in the weight of body which is called upthrust or buoyant force. this buoyant force is equal to the weight of liquid displaced by the body.
Buoyant force = weight of the water displaced by the block
Buoyant force = Volume of water displaced x density of water x g
= 55 x 10^-6 x 1000 x .8 = 0.539 N
True weight of the body = Weight of body in water + buoyant force
m g = 4.3 + 0.539 = 4.839
m = 0.4937 kg
Density of block = mass of block / volume of block
=
Density of block = 8977.7 kg/m^3
