PLS HELP TO SOLVE THIS
a=(17+5sinx+12cosx) / (17+5sinx-12cosx) = b
THEN a and b are equal to
OPTIONS ARE
1. 2/15 and 2
2. 2 and 2/15
3. 2/15 and 15/2
4. -1 and 1
PLS GIVE EXPLANATION
dx-(1+2xtany)dy=0
Please help me to solve that
Please help me again to solve this.
(e2y-ycosxy)dx-y(1-x2)dy=0
The solid compound shaft, made of three different materials, carries the two torques shown. (a) Calculate the maximum shear stress in each material. (b) Find the angle of rotation of the free end of the shaft. The shear moduli are 28 GPa for aluminium, 83 GPa for steel and 35 GPa for bronze.
xy' = y + 2 √xy
Is there a limit of value of modular ratio? If there is, what is the limit?
A spherical container of negligible thickness holding a hot fluid at 1400
and having
an outer diameter of 0.4 m is insulated with three layers of each 50 mm thick
insulation of k1 = 0.02: k2 = 0.06 and k3 = 0.16 W/mK. (Starting from inside). The
outside surface temperature is 300C. Determine (i) the heat loss, and (ii) Interface
temperatures of insulating layers.
need explaination plss..
1434 (fl. singer 4th edition)
Determine the maximum torque that can be applied at 1.0 m from the right end of the shaft, without causing excessive rotation.
what superelevation is required on a 40 railway curve for zero resultant flange pressure on a car running at a speed of 64kph?
C. What is the resultant flange pressure on a 450KN car moving around this curve at a speed of 96KPH.
Gage G of the track is 1.50m. (A 40 curve is one whose chord is 30.5m)
17. At what speed must a 1000kg car approach a ramp which has a slope and 12m high at the top such that it will just coast to the top. Assume the constant retarding force due to friction, wind, etc. to be 60kg.
