The velocity ratio in case of an inclined plane inclined at angle θ to the horizontal and weight being pulled up the inclined plane by vertical effort is
The polar modulus for a hollow shaft of outer diameter (D) and inner diameter (d) is
A boat sails across a river with a velocity of 10 km/hr. If resultant boat velocity is 14 km/hr, then what is the velocity of river water?
Which of the following is incorrectly matched?
A helical gear made of plain carbon steel has face width 10 times the normal module. If number of teeth on pinion and gear are 20 and 60 respectively, then what will be the wear strength of helical gear? (Assume mn = 5, BHN = 200 & Ψ = 24o)
The particular solution of the differential equation is
There are 200 individuals with a skin disorder, 120 had been exposed to the chemical c1, 50 to chemical c2, and 30 to both chemicals c1 and c2. find the number of individuals exposed to chemical c2 but not chemical c1
Let U= set of individuals suffering from the skin disorder
A= set of individuals exposed to the chemical c1
B= set of individual exposed to the chemical c2
Then n(u)=200, n(A)=120, n(B)=50 and n(A∩B)=30
Similarly, B=(B−A)∪(A∩B)
∴n(B)=n(B−A)+n(A∩B)
∵n(B−A)∩(A∩B)=φ
∴n(B−A)=n(B)−n(A∩B)
=50−30=20
Hence, 20 individuals exposed to chemical c2 but not to chemical c1
Two masses are placed on the opposite side of the shaft axis in the same axial plane as shown in the figure. The masses to be added at locations. A and D respectively at radius 40mm which will produce complete static and dynamic balance
Since the given configuration is already in static balance, therefore for dynamic balancing,
A square plate hangs in water from one of its corners and its centroid lies at 8m from the free water surface. Find the total pressure force on the top half of the plate
