Answer:
Step-by-step explanation:
The two force F1 and F2 are represented by vectors with initial points that are at the origin.
the terminal point of the vector is point P(1, 1, 0)
Therefore, the direction of the vector force is
The unit vector in the direction of force will be
The magnitude of the force is 40lb, so the force will be
The terminal point of its vector is point Q(0, 1, 1)
Therefore, the direction of the vector force is
The magnitude of the force is 60lb, so the force will be
The resultant of the two forces is
The magnitude force will be
to (1 decimal place)=55.7lb
b) The direction angle of force F
The angle formed by F and x axis
The angle formed by F and y axis
The angle formed by F and z axis
Answer:
10
Step-by-step explanation:
If there is a direct relation between two variables x and y then it can be represented as
y = kx ,
where y is dependent variable
x is independent variable
k is constant of variation
_____________________________
First condition
y = 400
x = r
using y = kx then relationship will be
400 = kr
finding k here
k = 400/r
Second condition
y = r
x = 4
using y = kx then relationship will be
r = 4k
finding k
k = r/4
since in both condition equation is same
thus, value of k will also be same
thus,
400/r = r/4
=> 400*4 = r*r
=> 1600 = r^2
Thus, 40 is the value of r
k = r/4 = 40/4 = 10
Thus, constant of variation is 10 which is correct choice.
To cross validate
k = 400/r = 400/40 = 10
