(a) breaking stress to working stress (b) endurance limit to
yield stress
(c) elastic limit to ultimate stress (d) yield stress to working
stress
2. The steering of a ship means
(a) Movement of a complete ship up and down in vertical plane
about transverse axis
(b) Turning of a complete ship in a curve towards right or left,
while it moves forward(c) Rolling of a complete ship side-ways

(a) #irectly proportional to speed (b) directly proportional to
(speed)$
(c) %nversely proportional to speed (d) inversely proportional
to (speed)$
4. The factor which affects the critical speed of a shaft is
(a) diameter of disc (b) span of shaft
(c) eccentricity (d) all of these
5. The danger of breakage and vibration is maim!m
(a) &elow the critical speed (b) near the critical speed
(c) 'bove the critical speed (d) none of these
" The maim!m fl!ct!ation of speed is the

speed
(b) #ifference of the maximum and minimum speeds
(c) um of maximum and minimum speeds
(d) *ariations of speed above and below the mean resisting
tor+ue line
