Answer & Explanation:
"The force <em>on a cutting tool</em> are 2600N vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "ON the tool" is upwards. We will accept the statement as it is (downwards).
Since the two forces are acting at right angles to each other, the resultant can be found using Pythagoras theorem, namely
resultant = sqrt(2600^2+2100^2) = 3342 N (approx.)
The angle can be found using the arcTangent function, or
angle = arcTangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 N force is acting downwards.
Answer:
15.78 m
Explanation:
Length = resistance×area/resistivity
Resistance = 15 ohms
Area = πd^2/4 = 3.142×(0.15/1000)^2/4 = 1.767375×10^-8 m^2
Resistivity = 1.68 ohm-meter
Length = 15×1.767375×10^-8/1.68×10^-8 = 15.78 m
Answer:
86584N
132.306 mm
Explanation:
Q = 274
Modulus of elasticity = 118 gpa
1.
Area = 316mm² without plastic deformation
F = QA
= 274x10⁶x316x10^-6
= 274000000 x 0.000316
= 86584 N
This is the maximum load.
2.
Max length =
L = 132(1 + 274x10⁶/118x10⁹)
L = 132(1+274000000/118000000000)
L = 132(1+0.002322)
L = 132(1.002322)
L = 132.306
This is the maximum length to which it may be stretched without causing plastic deformation.
