Question 5
A petrol engine has a bore of 10 cm and a stroke of 15 cm. The work done is 1000 joules. If the clearance volume is 200 cc then the heat added(Joules) will be:
Question 6
The system shown in the figure consists of block A of mass 5 kg connected to a spring through a massless rope passing over pulley B of radius r and mass 20 kg. The spring constant k is 1500 N/m. If there is no slipping of the rope over the pulley, the natural frequency of the system is rad/s.
Question 7
Consider a cantilever beam, having negligible mass and uniform flexural rigidity, with length 0.01 m. The frequency of vibration of the beam, with a 0.5 kg mass attached at the free tip, is 100 Hz. The flexural rigidity (in N.
) of the beam is ________
) of the beam is ________ Question 8
In a linearly hardening plastic material. The true stress beyond initial yielding
Question 9
A single point cutting tool with 
rake angle is used in an orthogonal machining process. At a cutting speed of 180 m/min. the thrust force is 490 N. If the coefficient of friction between the tool and the chip is 0.7, then the power consumption (in kW) for the machining operation is _______

A company places orders for supply of two items A and B. The order cost for each of the items is Rs. 300/order. The inventory carrying cost is 18% of the unit price per year per unit. The unit prices of the items are Rs. 40 and Rs. 50 respectively.
The annual demands are 10,000 and 20,000 respectively.
The annual demands are 10,000 and 20,000 respectively.
A supplier is willing to give a 1% discount on price, if both the items are ordered from him and if the order quantities for each item are 1000 units or more. Is it profitable to avail the discount?
