Answer:
Fa = 57.32 N
Explanation:
given data
mass = 5 kg
acceleration = 4 m/s²
angular velocity ω = 2 rad/s
solution
first we take here moment about point A that is
∑Ma = Iα + ∑Mad ...............1
put here value and we get
so here I = (
) × m × L² ................2
I = (
) × 5 × 0.8²
I = 0.267 kg-m²
and
a is = r × α
a = 0.4 α
so now put here value in equation is 1
0 = 0.267 α + m r α (0.4) - m A (0.4)
0 = 0.267 α + 5 (0.4α) (0.4 ) - 5 (4) 0.4
so angular acceleration α = 7.5 rad/s²
so here force acting on x axis will be
∑ F(x) = m a(x) ..............3
a(x) = m a - m rα
put here value
a(x) = 5 × 4 - 5 × 0.4 × 7.5
a(x) = 5 N
and
force acting on y axis will be
∑ F(y) = m a(y) .............. 4
a(y) - mg = mrω²
a(y) - 5 × 9.81 = 5 × 0.4 × 2²
a(y) = 57.1 N
so
total force at A will be
Fa =
...............5
Fa =
Fa = 57.32 N
Answer:
True
Explanation:
By definition of steady flow we have

where f(x,y,z,t) is any property of the system under consideration
=> f(x,y,z,t) = constant

Mechanized agriculture refers to agricultural machinery capable of facilitating and enhancing agriculture. Mechanized agriculture does not require moving the soils and therefore is hard for water to enter into it.
<h3>What is mechanized agriculture?</h3>
Mechanized agriculture refers to the use of different technologies (e.g., precision agriculture GPs) in order to increase farmworker productivity.
Mechanized agriculture is a common practice in developed countries (MEDCs), whereas this practice is relatively uncommon in developing countries (LEDCs).
The techniques of mechanized agriculture do not require moving the soils and therefore is hard for water to enter into it.
