An air-standard otto cycle has a compression ratio of 8 and temperature and pressure at the beginning of the compression process are 560°r and 14.7 lbf/in2 respectively. the heat addition per unit mass of air is 400 btu/lb. determine the (a) maximum temperature, in 'r (b) maximum pressure, in lbfin (c) heat rejected, in btu/lb (d) thermal efficiency 10 pts] [10 pts] 10 pts 10 pts) solve the problem using the cold-air standard assumption using cv 0.172 btu/lb. r and k 14

Janelle made a hypothesis bout the uneven temperatures inside her house during winter. she believes that 50% of the ducts are blocked and she plans to investigate. if she wants to prove her hypothesis using scientific processes what should she do next?

Aparticle of mass m is projected with an initial velocity v0 in a direction making an angle α with the horizontal level ground as shown in the figure. the motion of the particle occurs under a uniform gravitational field g pointing downward. (a) write down the lagrangian of the system by using the cartesian coordinates (x, y). (b) is there any cyclic coordinate(s). if so, interpret it (them) physically. (c) find the euler-lagrange equations. find at least one constant of motion. (d) solve the differential equation in part (c) and obtain x and y coordinates of the projectile as a function of time. (e) construct the hamiltonian of the system, h, and write down the hamilton’s equations (canonical equations) of motion.

Abanked road comer of radius 146 m is to be constructed. if the comer is designed for vehicles moving with a speed of 20.0 m/s, what should the banking angle be, in units of degrees?
