the probability that an engine will not start is .04. a rocket has four independent engines.

what is the probability that at least one of the engines does not start?

Solutions

Expert Solution

Given,

Probability engine does not start = 0.04

Probability engine start=1-0.04=0.96

Probability all engine starts = 0.96*0.96*0.96*0.96 =0.8493

Probability that at least one engine does not start = 1- Probability all engine starts

=1- 0.8493 = 0.1507

This gives the probability of at least one engine does not start.

A rocket has a mass of 1.40×04 kg and its engine has a thrust of 200×105 N. If its engines fire in the vertical direction for 1 min starting from rest, to what vertical height would it rise in the absence of air resistance? (To simplify things, assume the mass is constant. However, in reality the mass of rockets decreases substantially while rising)

Lakeview Engine, Inc., produces engines for the watercraft industry. An outside manufacturer has offered to supply several component parts used in the engine assemblies, which are currently being produced by Lakeview. The supplier will charge Lakeview $320 per engine for the set of parts. Lakeview’s current costs for those part sets are direct materials, $160; direct labor, $75; and manufacturing overhead applied at 100% of direct labor. Variable manufacturing overhead is considered to be 20% of the total, and fixed...

A reputable engine company has been making carbureted spark-ignition engines that operate with an equivalence ratio = 1.0 and a compression ratio of 9:1 for years. In order to control emissions, the engines operate with 20% exhaust gas recirculation (EGR) and a three-way catalytic converter. Since the company’s market share is steadily dropping, they consider hiring a MEC graduate to rescue them. The ambitious young engineer proposes a port fuel-injected (PFI) design, which operates lean at 0.7 with a high...

A mechanic is trying to tune the engines in a twin engine plane much like a string instrument can be tuned by listening to the beat frequency when two notes are played simultaneously. The mechanic has one engine running perfectly at a desired 4500 rpm and is trying to adjust the other to the same speed. He slowly detunes the second engine from a larger rpm until he first discerns a beat frequency amplitude that occurs once every 12 s....
