Chapter 4, Problem 20P

The tower crane is used to hoist the 2-Mg load upward at constant velocity. The 1.5-Mg jib BD, 0.5-Mg jib BC, and 6-Mg counterweight C have centers of mass at G1, G2, and G3, respectively. Determine the resultant moment produced by the load and the weights of the tower crane jibs about point A and about point B.

The tower crane is used to hoist the 2.1-Mg load upward at constant velocity. The 1.3-Mg jib BD, 0.9-Mg jib BC, and 6.5-Mg counterweight C have centers of mass at G1, G2, and G3, respectively. Determine the resultant moment in kN-m produced by the load and the weights of the tower crane jibs about point B. ( in kN.m and assume counterclock wise as positive, clockwise as negative) 4 m 9.5m -7.5 m G1 12.5 m 23 m
The railway crossing gate consists of the 100-kg gate arm having a center of mass at Ga and the 250- kg counterweight having a center of mas at GW. Determine the magnitude and directional sense of the resultant moment produced by the weights about point A. G₁ 2.5 m 0.75 m + Gw 0.5 m 0.25 m 1'm
Elements of the lower arm are shown in the figure. The mass of the forearm is 2.3 kg with mass center at G. Determine the combined moment about the elbow pivot O of the weights of the forearm and the 3.6-kg homogeneous sphere. What must the biceps tension force be so that the overall moment about O is zero? 50 mm 55 150 mm 2.3(9.81) N 3.6(9.81) N 325 mm
