The maximum friction force opposing the sliding is F 2 = Mgcosθμ s At some angle θ the block will be on the verge of sliding This is the maximum angle θ and occurs when F 1 = F 2 The maximum angle θ can be solved from this Answer θ max = atan μ s Hint and answer for Problem # 4 This is a good static equilibrium problem It is

### Main Distribution BoardsArabian Gulf Switchgear Ltd

Power Distribution is a system consisting of a Main Distribution Board MDB Sub Main Distribution Boards SMDBs and Final Distribution Boards by which the electrical energy is transmitted via branches to reach the exact end user An MDB is a panel or enclosure that houses the fuses circuit breakers and ground leakage protection units where the electrical energy which is used to

### PCB 90 degree anglesElectrical Engineering Stack

If you need to corner a trace more compactly then using a 90 degree or two 45 degree angles are both incorrect A 90 degree corner causes an impedance discontinuity when the trace width to increases by a factor of 2 at the 90 degree corner causing a sudden drop in impedance This will indeed cause reflections and radiate

### The basics of primary distribution circuits substation

A feeder is one of the circuits out of the substation The main feeder is the three phase backbone of the circuit which is often called the mains or mainline The mainline is normally a modestly large conductor such as a 500 or 750 kcmil aluminum conductor Utilities often design the main feeder for 400 A and often allow an emergency rating
