QUESTION 2 Two ropes, with tensions T1- 5 N and T2 - 2.5 N, pull on a pulley as shown in the figure T1 T. 2 The pulley is a uniformly dense cylinder with a radius of 5 cm and a mass of 2 kg. The pulley rotates around a frictionless axle that passes through its center. The pulley is initially at rest, but after the tensions are applied begins to rotate. What is the net work (in J) done...

A uniform plank of mass 30kg and length 20m is supported by two
ropes T1 and T2 attached as shown on the diagram. Two masses 20kg
and 25kg are suspended are shown to keep the plank in equilibrium.
Find the tension T1 and T2 due to the two ropes.
I'm having trouble with this question. Would love to see the
actual work, so I can understand the concept.

PLEASE SOLVE USING MATLAB
As shown, two weights are in state of static equilibrium, hanging from three strings of known lengths. Write 6 equations and solve them in MATLAB to determine the angles (0,, θ2,93) and tensions (T. T2, T3) of the strings. Hint: We can write 4 equations of equilibrium based on F 0and Fy- 0 for each mass. Two more equations are obtained by writing the displacement compatibility relations L1 cos(01)+L2cos(02) +Lacos(03) 8 L1 sin(θ 1 ) 0...

Suppose that we have two algorithms A1 and A2 for solving the same problem. Let T1(n) be the worst-case time complexity of A1 and T2(n) be the worst-case time complexity of A2. We know that: T(1)=1 T1(n)=15*T1(n/2)+n^2, n>1 T2(1)=1 T2(n)=80*T2(n/3)+20n^3,n>1 a. Use the master method to decide T1(n) b. Use the master method to decide T2(n) c. Which algorithms is more efficient? Why?
