A uniform 39.0 kg scaffold of length 6.6 m is supported by two light cables, as shown below. An 84.0 kg painter stands 1.0 m from the left end of the scaffold, and his painting equipment is 1.3 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables (in N) and the mass of the equipment (in kg)

Step 1
First, we need to find the total weight of the system, which includes the painter, the scaffold, and the painting equipment. Let's denote the mass of the equipment as $m_e$. The total weight is: $W_{total} = (39.0 + 84.0 + m_e)g$ Show more…

A uniform 50-kg scaffold of length 7.0 m is supported by two light cables, as shown below. A 60-kg painter stands 1.0 m from the left end of the scaffold, and his paint bucket is 1.5 m from the right end. If the tension in the left cable is twice that in the right cable, find the tensions in the cables and the mass of the bucket. mbucket = kg Tleft = N Tright = N
A uniform 60-kg scaffold of length 8 m is supported by two light cables, as shown below. A 90-kg painter stands 1.5 m from the left end of the scaffold, and his painting equipment-bucket is 2 m from the right end. If the tension in the left cable is twice that in the right cable, find the mass (in kg) of the equipment-bucket. 3.44 7.44 6.44 5.44
