5-5.14. A homogeneous cylinder 3 ft in diameter and weighing 400 lb is resting on two rough inclined surfaces as shown in Fig. P-5-5.14. If the angle of friction is 15°, find the couple C applied to the cylinder that will start it rotating clockwise. C= 251 ft-lb Ans. 5-5.15. Find the couple applied to the cylinder of Prob. 5-5.14 that will start counterclockwise rotation. mor -5-5.16. For the cylinder described in Prob. 5-5.14, determine the minimum horizontal force P applied tangentially. to the left at the top that will start counterclockwise rotation. E

Please us the method of superposition

The linkage in Figure 1 has link 3 perpendicular to the X axis and links 2 and 4 are parallel to each other. Find @3, 04, VP, α4, AA, AB, and Ap if ₂ = 15 rad/sec CW and α2 = 100 rad/sec² CW. Use an analytical method. B YA 02 2 04 X Figure 1 L₁ = 4.43 L2 = 2.75 L3 3.26 L4 2.75 AP = 1.63

Pls i need the counting of link and j1 and j2 with count on graph

A pole extends from the origin to point A. A wire connects points A and B. Values for the figure are given in the following table. Note the figure may not be to scale. Variable Value a 4.5 m 2 m 2.5 m 1.5 m a. Determine the position vector from point A to origin (r AO), express as a cartesian vector. b. Determine the position vector from point A to B (7AB), express as a cartesian vector. Round your final answers to 3 significant figures. k) m AO k) m TAB

how J1 is 4 please count it on the graph with explain. (And when do we count the link and the j1 twice??) explan with the formula of counting please
