Answer:
87.5
Step-by-step explanation:
-2
Let a, ß be the roots of x² + 2ax + b =0.......[1]
⇒a + ß = -2a and aß = b
By hypothesis
la-ß | ≤ 2m
⇒ (a-ß)² ≤ 4m²
⇒ (a+ß)²-4aß < 4m²
⇒ 4a²-4b ≤ 4m²
⇒a² - b ≤ m²......(2)
And discriminant of (1) is >0
⇒4a²-4b> 0
⇒ b <a²...... (3)
From (2) and (3)
a² > b≥ (a² - m²)
b = [a² - m², a²)
The equation for resolving couples will come in place

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
<h3>
Couple moment and Cartesian vector</h3>
Couple moment:This looks at the product of the forces acting on a body( in this context a steering wheel ) by the perpendicular distance that exist amidst the forces.
Cartesian vector:this is the representation of unit vectors by i and j along the x-axis and the y-axis, respectively.
Therefore, in calculating the <em>couple</em> moment t acting on the steering wheel, the equation for resolving couples will come in place

Using the unit vectors by i and j along the x-axis and the y-axis you'll express it as a Cartesian vector.
