Chapter 11, Problem 49P

The pulley-cable system supports the 150-lb weight. The weights of the pulleys and the horizontal bar ABC are negligible. Determine the cable tensions at A and C and the distance x.

Find the stable equilibrium position of the system described in Prob. 10.56 if m = 2.06 kg.

If d=2m and F-200N and the mass of ball 30 kg Determine the forces in cables AC and AB in equilibrium 1.5 m F -2 m- Maximum size for new files: 128MB

The backhoe and its contents have a combined weight of 300 kN and center of gravity at point G. Find the resulting force in cylinder AE and linkages AB and AD, indicating whether they are in Tension or Compression. Given:  L1 = 300 mm,   L2 = 75 mm,   L3 = 450 mm,   θ = 40 °,   Φ = 60 °.

Ignore the plot at the end of the question

the man is holding up the 35-kg ladder ABC by pushing perpendicular to ladder. The total length of the ladder is AC=6m. If maximum force that the man can exert is 400N at B which is 2m from A. determine the smallest angle, theta, at which the man can support the ladder

Draw the locations of G, M, and B for a floating body to be in stable equilibrium

The figure shows the Russel fracture traction device and a mechanical model of the leg. The leg is held in balance in the position indicated by the two weights attached to the two cables. The combined weight of the leg and cast is W=180 N. The horizontal distance between points A and B where the cables are attached to the leg is L=100 cm and the vertical distance is d=5 cm. Point C is the center of gravity of the cast and leg at three quarters of the L measured from point A (3L/4= 75 cm). The angle that cable 2 makes with the horizontal is measured as β=30°. Accordingly, in order for the leg to remain in balance in the shown position; a) Find the tensile force T1 in cable 1. (Write your result in N) Answerb) Find the tensile force T2 in cable 2. (Write your result in N) Answerc) Find the angle α of cable 1 with the horizontal. Response

The jib crane is designed for a maximum capacity of  7 kN, and its uniform I-beam has a mass of  240 kg. Plot the magnitude R of the force on the pin at A as a function of x through its operating range of x =  0.2 m to x =  3.7 m. On the same set of axes, plot the x- and y-components of the pin reaction at A. Do these plots on a separate piece of paper. Then answer the following questions in Wiley Plus as a check for your work.(a) What is the value of R when x =  1.9 m?(b) What is the value of R when x =  3.2 m?(c) Determine the minimum value of R and the corresponding value of x.(d) For what value of R should the pin at A be designed?
