Problem 6-108

The skid-steer loader has a mass of 1.18 Mg, and in the position shown the center of mass is at G1. If there is a 300-kg stone in the bucket, with center of mass at G2, determine the reactions of each pair of wheels A and B on the ground and the force in the hydraulic cylinder CD and at the pin E. There is a similar linkage on each side of the loader.

Step by Step Solution

Step 1 of 8

First, We’ll isolate and draw the free-body diagram of member ED

Note that the weight of the 300 -kg load is

Also note that there is another member with hydraulic cylinder attached to in on the other side of the loader, so using symmetry we can assume that the reaction forces are equal at both sides, ergo there is number 2 in front of the reaction forces
