If the length of a combined footing for two columns l meters apart is L and the projection on the left side of the exterior column is x, then the projection y on the right side of the exterior column, in order to have a uniformly distributed load, is (where x̅ is the distance of centre of gravity of column loads).?

LohaHridoy
  1. y = L - (l - x̅)
  2. y = L/2 + (l - x̅)
  3. y = L/2 - (l + x̅)
  4. y = L/2 - (l - x̅)

The brake power (B.P.) of the engine is given by (where W = Brake load or dead load in newtons, l = Length of arm in meters, N = Speed of engine in r.p.m., S = Spring balance reading in newtons, D = Dia. of brake drum in meters, and d = Dia. of rope in meters)?

Answer: Option 4 The brake power (B.P.) of the engine is given by -B.P = (Wl × 2πN)/60 watts -B.P = [(W - S) πDN]/60 watts - B.P = [(W - S) π...

Which direction is Sunny facing now Statements : I. If Sunny turns to his right and again turns to his right, he will be facing North. II. If Sunny walks some distance and turns left and again walks some distance, then his face will be towards left of Dinesh who is facing South.?

Answer: Option 3 From I, we conclude that Sunny is facing South, since a person facing South shall face North on turning to his right, twice. From II, we know that...
