A car is accelerating in the +x direction. At 2s the car is 100m from the starting point. After an additional 5s, it is 1.5km from the starting point.
Determine the average velocity of the car for the first 5s of its travel.
Determine the average velocity of the car for the entire period of its travel.

2. A burglar alarm for a car has a normally low switch on each of four doors. If any door is opened, the output of that switch goes HIGH. The alarm is set off with an active- LOW onput signal. What type of gate will provide this logic? Support your answer with an expaination.
Determine the acceleration of A4 on link 4 for the quick
return mechanism given below. Link 2 rotates 10 rad/sec CW.
Fixed link 0,04= 300mm, Driving link O2A = 100mm, 0 = 51° and B =
18º. Also find out coriolis component of acceleration and angular
acceleration of link 4.
A bar AB of 6mts length and 100 N weight is hinged at A.it supports a load of 25 kg at point B.the end B of the bar is connected to the wall by string BC . Determine the tension in the string and the reaction at A.
Determine the angle which the string would make with the horizontal,whan weights of the blocks A and B are such that
(a)WA=WB=W and
(b)WA=W,WB=2W.
A bar AB is hinged to the foundation at A and supported by strut CD is subjected to a horizontal 50 kN load at B,as shown in fig Determine the nature and magnitude of the forces in strut and also the reaction at A
for a pure sinosudial wave. what is the value of form factor and peak factor
A hollow circular tube T of length L = 15 in. is uniformly
compressed by a force P acting through a rigid plate (see
figure). The outside and inside diameters of the tube are
3.0 and 2.75 in., respectively. A concentric solid circular
bar B of 1.5 in. diameter is mounted inside the tube.
When no load is present, there is a clearance c _ 0.010
in. between the bar B and the rigid plate. Both bar and
tube are made of steel having an elastoplastic stress-
strain diagram with E = 29 x 103 ksi and 𝜎Y = 36 ksi.
(a) Determine the yield load PY and the corresponding
shortening ẟY of the tube.
(b) Determine the plastic load PP and the corresponding
shortening ẟP of the tube.
Knowing that a 0.02-in. gap exists when the
temperature is 75℉, determine (a) the temperature at
which the normal stress in the aluminum bar will be
equal to - 11 ksi, (b) the corresponding exact length
of the aluminum bar.
