A 22-lb block B rests as shown on a 28-lb bracket A. The coefficients of friction are μs=0.30μs=0.30 and μk=0.25μk=0.25 between block B and bracket A, and there is no friction in the pulley or between the bracket and the horizontal surface. solved in a previous part. max weight of block C if block B is not to slide on bracket A is 5.045 lbs. Please solve for the acceleration of each Block

It is decided to install several single-jet Pelton wheels to produce a total power of 18 MW. The available head is 246 m. The wheel rotational speed is 650 rpm and the speed ratio (❤) = 0.46. The diameter of the nozzle (jet) is limited to be 0.167 m with a Cv of 0.95. The efficiency of each turbine is 87%. Determine: (1) The number of Pelton wheels to be used, and (2) The bucket angle.

Please show All work and fill it in thermodynamics

(I) [40 Points] Using centered finite difference approximations as done in class, solve the equation for O: d20 dx² + 0.010+ Q=0 subject to the boundary conditions shown in the stencil below. Do this for two values of Q: (a) Q = 0.3, and (b) Q= √(0.5 + 2x)e-sinx (cos(5x)+x-0.5√1.006-x| + e −43*|1+.001+x* | * sin (1.5 − x) + (cosx+0.001 + ex-1250+ sin (1-0.9x)|) * x - 4.68x4. For Case (a) (that is, Q = 0.3), use the stencil in Fig. 1. For Case (b), calculate with both the stencils in Fig. 1 and Fig 2. For all the three cases, show a table as well as a plot of O versus x. Discuss your results. Use MATLAB and hand in the MATLAB codes. 1 0=0 x=0 2 3 4 0=1 x=1 Fig 1 1 2 3 4 5 6 7 8 9 10 11 0=0 x=0 0=1 x=1 Fig 2
