Solution:
A block weighing 100 N is resting on a surface. The coefficient of friction between the block and the surface is 0.3. A horizontal force of 20 N is applied to the block. What is the magnitude of the frictional force acting on the block?
Solution:
The rules used to design trusses have various requirements. One of them is that smooth pins are not used to join the members.
Solution:
An object in undamped free vibration vibrates at its natural frequency. Calculating this natural frequency is crucial for resonance effect analysis. Consider an object with a mass of 20 kg and a spring constant of 500 N/m attached to it. What is the natural frequency of this object?
Solution:
A uniform circular ring of mass M and radius r is rotating with an angular speed ω about an axis passing through its center and perpendicular to its plane. Two identical beads of mass m are attached at two diametrically opposite points. Find the new rotational speed of the ring.
