Determine the chebyshev spacing for function y = log 10 X for the range 1≤ X ≤10 where three precision positions are required . Determine θ 2 , θ 3 and θ 2 , θ 3 if 45ᶿ is starting position and 105ᶿ is finishing position of input link and 135ᶿ is starting position and 225ᶿ is finishing position of output link.
A four bar mechanism is used to generate the function Y= 1/x for the range 1≤ X ≤3. Find the three precision positions from chebyshev spacing. If the initial values for the crank angle and follower angle is 30◦ and 200◦ respectively.
Take Δ θ=Δ ɸ 90ᶿ. Find the corresponding values of θ And ɸ
horizontal cylindrical tank filled with liquid but we dont know it height of liquid so how we find out and how we calculate volm of liquid only we know about length or diameter of cylinder
Assume 2 kg of hydrogen (Item B 28) are initially at 40 atm, 100 K. (a) If the hydrogen changes pressure to 1 atm without a change of temperature, find the changes of enthalpy and entropy. (b) If the hydrogen changes temperature to 35 K with no change of entropy, find the change of pressure and enthalpy.
In a single slider crank mechanism, the length of crank and connecting rod are
125 mm and 500 mm respectively. The crank speed is 600 RPM Clockwise.
When the crank has turned 45° from the inner dead centre position, determine
the velocity of the slider

gear. The bevel pinion is mounted on a shaft driven by a V-belt on pulley. If pulley 2 rotates at
1200 r.p.m. in the direction shown, find the speed and direction of rotation of gear 9.
a compound gear train in which, wheel A is fixed to the driving shaft, B-C are
compounded , D is idle, and E is fixed on the driven shaft. If gear A rotates at 1000 r.p.m find
the speed and direction of E. driven shaft.
Stone A is hurled vertically upwards from a tower of height h with a speed vA0 . Simultaneously, stone B is thrown vertically upwards from the ground with a speed of vB0.
Given:
h=30m ; vA0=15m/s ; vB0=25m/s ; g=9.81m/s2 Find:
1. At which height and time do the stones fly past another?
2. At this time, what is the speed of stone A relative to stone B?
A steam engine isentropically expands 5 kg/sec of steam from 0.68 Mpa,
220°C, the exhaust is dry and saturated. Determine (a) the work of nonflow
process (b) the final temperature, and (c) the work of a steady flow process.
