Cylinders Are in Contact Along an Inclined Plane $W$ ), and Both Are Supported by a Wall Where the Cylinder

Multiple Choice

cylinders are in contact along an inclined plane. The upper cylinder (weight is 2.5W) rests against the lower cylinder (weight $W$ ) , and both are supported by a wall where the contact force is $N _ { 1 }$ . Assume that all friction forces are negligible. An expression for contact force $N _ { 1 }$ in terms of load variable $W$ is:

A) 1.75W
B) 3.5W
C) 1.57W
D) 2.01W
