Answer:
The drying time is calculated as shown
Explanation:
Data:
Let the moisture content be = 0.6
the free moisture content be = 0.08
total moisture of the clay = 0.64
total drying time for the period = 8 hrs
then if the final dry and wet masses are calculated, it follows that
t = (X0+ Xc)/Rc) + (Xc/Rc)* ln (Xc/X)
= 31.3 min.
Answer:
Horizontal force = 89.2 N
Explanation:
The frictional force = coefficient of friction * magnitude of the force (weight of the body) * cos theta
Substituting the given values, we get -
Frictional Force = 0.3*300 * cos 25 = 89.2 N
Horizontal force = 89.2 N
Answer:
This is self locking.
Explanation:
Given that
Diameter d= 40 mm
Pitch (P)= 6 mm
Torque T= 1 KN.m
Friction(μ) = 0.1
Thread is double square.
Condition for self locking
L= n x P
N= number of start
Here given that double start so n=2
L=2 x 6 = 12 mm
(μ = 0.1)
So from we can that this is self locking.
Answer:The distinction between a permanent magnet and an electromagnet is essentially one in how the field is created, not the properties of the field afterwards. So electromagnets still have two poles, still attract ferromagnetic materials, and still have poles that repel other like poles and attract unlike poles.
Explanation:
Answer:
In engineering, the most basic or primary unit of measurement used for drafting is the <u>millimeter</u> and the <u>meter</u>, followed by the <u>kilometer</u>
Explanation:
Based on the the SI system of units, in engineering, the most basic or primary unit of measurement used for drafting is the millimeter and the meter, followed by the kilometer
The millimeter is used in mechanical and an architectural drawing, the meter is used architectural drawing, while civil dimensioning make use of the kilometer
In the US it is customary to use the inches and a fraction of an inch is used as a scale in scale drawings
