A polymer beam was designed to sit on three supports, but the middle support was accidentally placed 0.3 mm lower than the others. Determine the magnitude of the vertical reaction force at B after moment M = 0.74 N·m is applied and causes the beam to rest on all three supports. Let a = 55 mm, b = 55 mm, and EI = 0.85 N·m2. Assume that the supports allow rotation, no deflection at A and C, and no additional deflection at B.

A straight polymer beam is bent due to moment M = 0.67 N·m. Determine the magnitude of the beam’s largest vertical deflection between A and B. Let a = 104 mm, b = 76 mm, and EI = 0.80 N·m2. Assume that the supports allow rotation but not deflection at A and B.

A new social media application is being developed using MongoDB. The architects want to ensure that the application’s data store provides multiple copies of data for protection against data loss and automatically elects a new primary node if the current one becomes unavailable, ensuring continuous availability for write operations. Question: Which MongoDB component setup is specifically designed to achieve data redundancy and automatic failover for write operations?
