Answer:
M_c = 61.6 Nm
Explanation:
Given:
F_a = 2.5 KN
Find:
Determine the moment of this force about C for the two casesshown.
Solution:
- Draw horizontal and vertical vectors at point A.
- Take moments about point C as follows:
M_c = F_a*( 42 / 150 ) *88
M_c = 2.5*( 42 / 150 ) *88
M_c = 61.6 Nm
- We see that the vertical component of force at point A passes through C.
Hence, its moment about C is zero.
Answer:
Newton per square meter (N/m2)
Explanation:
Required
Unit of ultimate tensile strength
Ultimate tensile strength (U) is calculated using:
The units of force is N (Newton) and the unit of Area is m^2
So, we have:
or
<em>Hence: (c) is correct</em>
