An acetal polymer block is fixed to the rigid plates at its top and bottom surfaces. if the top plate displaces 2 mm horizontally when it is subjected to a horizontal force p = 2 kn ,determine the shear modulus of the polymer. the width of the block is 100 mm. assume that the polymer is linearly elastic and use small angle analysi

Two rigid transformations are used to map δhjk to δlmn. the first is a translation of vertex h to vertex l. what is the second transformation? a reflection across the line containing hk a rotation about point h a reflection across the line containing hj a rotation about point k

Along wire carrying a 4.2 a current perpendicular to the xy-plane intersects the x-axis at x=−1.7cm. a second, parallel wire carrying a 3.0 a current intersects the x-axis at x=+1.7cm. part a at what point on the x-axis is the magnetic field zero if the two currents are in the same direction? express your answer to two significant figures and include the appropriate units.
