Concept explainers

It is defined as, two or more elements like beams or any two or more force members, which when assembled together, behaves like a complete structure or as a single structure. They generally consist of two force member which means any component structure …

Equilibrium Equations

If a body is said to be at rest or moving with a uniform velocity, the body is in equilibrium condition. This means that all the forces are balanced in the body. It can be understood with the help of Newton's first law of motion which states that the res…

Force Systems

When a body comes in interaction with other bodies, they exert various forces on each other. Any system is under the influence of some kind of force. For example, laptop kept on table exerts force on the table and table exerts equal force on it, hence th…

Chapter 3, Problem 3.12P

Instead of using the system shown in Figure 3.2.6a to raise the mass m 2 . An engineer proposes to use two simple machines, the pulley and the inclined plane, to reduce the weight required to lift m 2 . The proposed design is shown in Figure P3.12. The pulley inertias are negligible. The available horizontal space limits the angle of the inclined plane to no less than 30°.

Suppose that the friction between the plane and the mass m 2 is negligible. Determine the smallest value m 1 can have to lift m 2 . Your answer should be a function of m 2 and θ .

In practice, the coefficient of dynamic friction μ d between the plane and the mass m 2 is not known precisely. Assume that the system can be started to overcome static friction. For the value of m 1 = m 2 / 2 , how large can μ d be before m 1 cannot lift m 2 ?
