- The man pushes the 120-lb homogeneous crate with the horizontal force P. Determine the largest distance h for which the crate will slide without tipping.arrow_forwardCan the uniform bar of weight W remain at rest in the position shown?arrow_forwardThe homogeneous bar AB weighs 25 lb. Determine the magnitudes of the forces acting on the bar at A and B. Neglect friction.arrow_forward
- Both pulleys are fixed to the shaft and as the shaft turns with constant angular velocity, the power of pulley A is transmitted to pulley B. Determine the horizontal tension T in the belt on pulley B and the x, y, z components ofreaction at the journal bearing C and thrust bearing D if θ = 0°. The bearings are in proper alignment and exert only force reactions on the shaft.arrow_forwardThe mass center G of the 1300-kg rear-engine car is located as shown in the figure. Determine the normal force under each tire when the car is in equilibrium. State any assumptions.arrow_forwardWhen the 0.05 kg T-shaped body, which has a height of 80 mm and is 120 mm wide, is in the position shown, the torsional spring at O is pre-tensioned to exert a 0.75 Nm clockwise couple on the body. Determine the force P required to break contact at C. The body is in a vertical plane, so the weight does have an influence. What is the moment of the weight of the body about point O?arrow_forward
- 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?arrow_forwardThe horizontal steel shaft has a mass of 500 kg and is suspended by a vertical cable from A and by a second cable BC which lies in a vertical transverse plane and loops underneath the shaft. Calculate the tensions T1 and T2 in the cables. (First part of the question: what is W, theta and d?)arrow_forwardThe jib crane is designed for a maximum capacity of 14 kN, and its uniform I-beam has a mass of 270 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 = 4.0 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. (You can disregard the plot, I only need a, b, c, and d)arrow_forward
