Question

Problem: Generate the Front Panel and Block Diagram by using LabView Program

4. Dragging Dresser.vi It's moving day and you are dragging a heavy dresser at constant velocity across the horizontal floor of your new apartment as shown in Figure 3.1. The force you are applying to the dresser has magnitude F, and it is directed at angle & above the horizontal. The weight of the dresser is W, and the coefficient of kinetic friction between it and the floor is u. O o FIG. 3.1 Problem 5

  

Note: Please, I need Front Panel and Block Diagram. Also, the answer of question (b).

Answer 1

clear
clc
prompt = 'Enter the mue value: ';
mue = input(prompt)
figure;hold on;
for i=1:90
theta(i) = i;
F_(i) = mue/(cosd(theta(i))+mue*sind(theta(i)));
end
plot(theta,F_)
legend(strcat('mue=',string(mue)))
hold off

figure;hold on;
Mue = [0.1,0.4,1];
for j=1:3
for i=1:90
theta(i) = i;
F_(i) = Mue(j)/(cosd(theta(i))+Mue(j)*sind(theta(i)));
end
plot(theta,F_)
end
grid on
xticks([0:5:100])
yticks([0:0.05:1])
legend('mue=0.1','mue=0.4','mue=1')

1 mue=0.5 0.9 0.8 0.7 0.6 0.5 0.4 0 10 20 30 40 50 60 70 80 90 mue=0.1 mue=0.4 mue=1 1 0.95 0.9 0.85 0.8 0.75 0.7 0.65 0.6 0.55 0.5 0.45 0.4 0.35 0.3 0.25 0.2 0.15 0.1 0.05 0 0 5 10 15 20 25 30 35 40 45 50 55 60 65 70 75 80 85 90

From the figure, we can see that

for mue=0.1, minimum angle is 5 degrees at which required force is less.

for mue=0.4, minimum angle is 20 degrees at which required force is less.

for mue=1, minimum angle is 45 degrees at which required force is less.
